LandscapAR is a new form of augmented reality (AR) app that invites users to create intriguing islands and terrains. Just sketch the elevation lines on a real piece of paper and it will be directly translated into a 3D landscape!

Create your own favorite tropical island with as many hills, mountains and valleys as you wish and visualize it on your table top at home in full 3D. Walk around your creation and view the islands from all perspectives.

Note that the paper should be distinctly visible from the background, that is, the paper should be as bright as possible and the background as dark as possible. Furthermore, you should use a thick dark pen.

The aim of the app is to go beyond the creation of user defined landscape while encouraging artistic creativity. We welcome you on this new way of creative artistry and augmented reality where the real world sketch meets the virtual terrain you build! You can share your creations with us on our facebook website.

Sky Map is a hand-held planetarium for your Android device. Use it to identify stars, planets, nebulae and more.

Originally developed as Google Sky Map, it has now been donated and open sourced.

Comet Neowise
Apologies for the delay in updating the app to include Comet Neowise. The update was stuck being reviewed by Google for many days.

Troubleshooting/FAQ
The Map doesn't move/points in the wrong place
Make sure you haven't switched into manual mode. Does your phone have a compass? If not, Sky Map cannot tell your orientation. Look it up here: http://www.gsmarena.com/

Try calibrating your compass by moving it in a figure of 8 motion or as described here
https://www.youtube.com/watch?v=k1EPbAapaeI.
Are there any magnets or metal nearby that might interfere with the compass? Try switching off "magnetic correction" (in settings) and see if that is more accurate.

Why is autolocation not supported for my phone?
In Android 6 the way permissions work has changed. You need to enable the location permission setting for Sky Map as described here:
https://support.google.com/googleplay/answer/6270602?p=app_permissons_m

The Map is jittery
Try adjusting the sensor speed and damping (in settings). We have a better solution coming soon!
Do I need an internet connection?
No, but some functions (like entering your location manually) won't work without one. You'll have to use the GPS or enter a latitude and longitude instead.

Can I help test the latest features?
Sure! Join our beta testing program and get the latest version.

Légköri nyomás és magasságmérő.

# data[].attributes.attachment_link.readable_text
A barométer és az magasságmérő egy egyszerű alkalmazás a légköri nyomás és magasság mérésére.

Az alkalmazás a következőket használja:
- beépített GPS,
- beépített nyomásérzékelő / barométer (ha a készülék nem rendelkezik barometrikus érzékelővel, akkor az alkalmazás a légköri nyomásadatokat az interneten keresztül a legközelebbi meteorológiai állomásról lekéri),
- automatikus magasság és légköri nyomás kalibrációs algoritmus, helyi meteorológiai állomás adatai alapján.

Barométer és magasságmérő funkciók:
- pontos tengerszint feletti magasságmérés (a GPS-től és más érzékelőktől),
- a barometrikus nyomás pontos mérése (ha a készülék nyomásérzékelővel van felszerelve és az online adatok ellenőrzése)
- GPS-koordináták, hely, ország neve
- a helyi meteorológiai állomás információi és aktuális időjárási adatai (ha rendelkezésre állnak).
- külső hőmérséklet,
- szélsebesség,
- láthatóság,
- páratartalom, higrométer (ha a készülék megfelelõ érzékelõkkel van ellátva).

Egy barométer vagy magasságmérő követők példaként szolgáló alkalmazása:
- az egészség és az orvos - az atmoszférikus nyomás figyelemmel kísérésével előkészíthetők nyomáspróbákra, fejfájásokra, migrénre és rossz közérzetre,
- a halászok és horgászok számára, akik a halászatot és vitorlázást - a légköri nyomást és az időjárást nyomon követik, növelheti a jó halászati ​​esélyeket,
- sportolók és turisták,
- az időjárás, a levegő hőmérséklete, szélsebességének meghatározása, előrejelzése és ellenőrzése,
- a helyszín ellenőrzéséhez,
- ellenőrző nyomásra és magasságra vonatkozó pilóták esetében,
- a tengerészek, a sémanok és a szörfösök ellenőrizhetik a szelet.

Ez a barométeres nyomkövető egyszerűbb, mint egy aneroid vagy higanybarométer használata. A Barométer és az Altimeter tracker ingyenes, könnyen használható, egyszerű és praktikus.

Figyelem! Egyes hordozható eszközök (tabletták, telefonok, okostelefonok) nem rendelkeznek beépített nyomásérzékelővel. Ezen készülékeknél a mérések kevésbé pontosak lehetnek, mivel ezek a helyi meteorológiai állomás adatai alapján készülnek.

Folyamatosan fejlesztjük ezt az alkalmazást, ha látunk valamit, ami javítható, küldje el nekünk az exatools@gmail.com címen. Ha tetszik ez az alkalmazás, akkor 5 csillaggal arányos.

Élvezze és jól érezze magát ezzel az alkalmazással!

What is it?
An app for creating digitally interactive scavenger hunts to lead the player on a path of discovery.

What can it be used for?
You can create a digital timeline of events / places of interest tour, with the use of GPS co-ordinates and pre-placed codes. Excellent for ice-breaking exercises, historical / archaeological sites, or more simply presenting a vision for the future or event the past.

More!
Actionbound is an app for playing digital scavenger hunts by means of installed digital content in the physical world.

The content is filled in by the users at actionbound.com making actual surroundings a backdrop for the game. We call these interactive mobile rallies "Bounds", essentially a collection of diverse tasks, e.g., taking pictures, dancing, playing a game etc., linked to a specific location.

The program quite literally augments our reality by enhancing peoples' real-life interaction whilst using their smart phones and tablets. Apart from the altruistic goal of helping people to discover "their environment by learning more about its history, politics and culture", the free app is payable for corporate clients, who can use Actionbound for team-building events and the likes.

Actionbound is an interactive app-based game approach for smart phones and tablets: Players are invited to accomplish tasks, which can be defined through the so-called Bound-Creator on the website actionbound.com, in order to playfully discover their environment by learning more about its history, politics and culture. In contrast to a geocache or a scavenger hunt Actionbound requires the players to create their own content. On the Actionbound website anyone can generate easily and without any programming skills his / or her own "Bounds", which means an interactive mobile rally.

1 Creating a Climate Chart

1.1 Map

When the web application is started, a map (1) is available that allows the user to select a region for generating a climate diagram. The most common tools are available for this purpose:

Mouse interaction - scroll wheel: zoom in/out

+/-: zoom in/out (2)

Select Base Map (3)

ESRI Base Map

OpenStreetMap

1.2 Select a Location

The selection of a location is quite easy and is done by clicking on a position in the map. Basically, there are two types of data sets available - raster data (see 1.2.1) and station data (see 1.2.2).

In addition, it is also possible to select a position on the map by entering coordinates into the filter menu. You can find it under the map tile (1). In this case a raster cell at this position is selected.

1.2.1 Raster Data

Once you selected a raster data set and clicked on a location, the corresponding raster cell is shown on the map in blue (1). Within this grid cell the resulting climate diagrams are identical. Another indicator that you are seeing raster instead of station data is the note "Climate Cell" at the top of the information popup (2). This popup also contains information about the name of the place you have selected (3) as well as information about the climate classes according to Köppen-Geiger, the altitude and the selected time period (4). With the button "Create Charts" a diagram is created below the map (5).

1.2.2 Station Data

If you click on one of the brown marked dots on the map, a weather station is selected. Once activated the color will change to blue (1).

You can also see that you have selected a station by the note "Climate Station" in the popup (2). This popup also contains information about the name of the place you have selected (3) as well as information about the climate classes according to Köppen-Geiger, the altitude and the selected time period (4). With the button "Create Charts" a diagram is created below the map (5).

1.3 Filter Options

1.3.1 Data Sets

Overall, four data sets are available for the generation of climate charts.

The weather stations' data set is part of the Global Historical Climatology Network (GHCN). This data set is automatically selected whenever a user clicks on a station (cf. 1.2.2).

In addition, three different raster data sets can be used to generate climate diagrams. Select one of these data sets before clicking on a location in the map. The selection menu is located beneath the map.

After you have chosen the preferred data set, you can select a location in the map.

You can find more information about the datasets in the menu "Datasets & Software".

1.3.2 Time Period

Climate diagrams are often generated for a period of at least 30 years. The web application ClimateCharts.net offers the possibility to adapt this period according to your own requirements. For this purpose, a slider for adjusting the period (1) is available. The Dark grey area shows the maximum time period in which data (independent of the selected dataset) is available. The maximum available time period for the selected data set (2) is shown in white. The length of this bar can vary depending on the selected data set. The selected time period can be adjusted individually by moving the upper and lower limits (3) of the light grey bar.

Only the data of the selected period is processed and displayed in the climate chart. The "Reset" button is used to set the most recent time period with a length of 30 years (4).

2 Visualizations

Currently, three different types of climate charts can be generated. After you have created a climate chart with the button "Create Chart" you will get the following view:

In the upper left corner (1) you can switch between the three different visualizations.

Walther-Lieth Climate Chart (see 2.1)

Distribution Chart (see 2.2)

Availability Chart (see 2.3)

In the default setting, the Walter-Lieth Chart is displayed after generation.

2.1 Walter-Lieth Climate Chart

2.1.1 Structure of the Walter-Lieth Chart

The Walter-Lieth Chart contains a number of components, which will be explained in the following:

The location's name. A gazetteer is used to generate the name (https://www.geonames.org/). Alternatively, you can set a name manually.

The location's coordinates.

Elevation of the location. For this information, the gazetteer "Geonames" is used as well.

Köppen-Geiger Climate Class. (Markus Kottek, Jürgen Grieser, Christoph Beck, Bruno Rudolf and Franz Rubel. 2006. "World Map of the Köppen-Geiger climate classification updated." Meteorologische Zeitschrift 15 (3): 259-263. https://dx.doi.org/10.1127/0941-2948/2006/0130.)

Selected time period

Visualization of climate data according to Walter-Lieth (1967)

Table of the average monthly values used for temperature and precipitation sums.

Mean annual temperature and annual precipitation values

Information on the completeness of the data within the selected time period

Data source (see 1.3.1)

Option to display a bar chart

2.1.2 Understanding the Walter-Lieth Chart

The Walter-Lieth Chart is an easy way to show information about the climatic conditions at a selected location The chart visualizes mean monthly temperatures (1) and mean monthly precipitation sum values (2). The values temperature and precipitation have a ratio of 1:2 up to a value of 100 mm mean monthly precipitation. This ratio changes to 1:10 if precipitation exceeds 100 mm.

The resulting intersections between the temperature and precipitation curves create areas of different classifications (color):

Yellow: The temperature curve lies above the precipitation curve. Arid or semi-arid conditions prevail.

Light blue: The precipitation curve lies above the temperature curve. Humid conditions prevail.

Dark blue: The precipitation curve is clearly above the temperature curve (note change in the scaling of the precipitation axis). These conditions are also called per-humid (monthly precipitation sum > 100 mm).

2.2 Distribution Chart (Boxplot)

2.2.1 Structure of the Distribution Chart

The location's name. A gazetteer is used to generate the name (https://www.geonames.org/). Alternatively, you can set a name manually.

The location's coordinates.

Elevation of the location. For this information, the gazetteer "Geonames" is used as well.

Köppen-Geiger Climate Class. (Markus Kottek, Jürgen Grieser, Christoph Beck, Bruno Rudolf and Franz Rubel. 2006. "World Map of the Köppen-Geiger climate classification updated." Meteorologische Zeitschrift 15 (3): 259-263. https://dx.doi.org/10.1127/0941-2948/2006/0130.)

Selected time period

Distribution chart (box plot) for the mean monthly temperatures during the selected period

Distribution chart (box plot) for the monthly precipitation sums during the selected period

Data source (see 1.3.1)

Adjustment of the scaling of the y-axis.

Relative = based on the selected data

Fixed = based on all data sets

2.2.2 Understanding the Distribution Chart

This chart visualizes the monthly distribution of the climate parameters included in the Walter-Lieth Chart using a box plot. This kind of chart visualizes the distribution of different parameters. Here, the average sums of monthly temperature and precipitation values are shown. The box plot include:

Median (middle value of the data set)

First quartile (25th Percentile, Q1)

Third Quartile (75th Percentile, Q2)

Interquartile Range (IQR, 25th to the 75th percentile; Box)

Whiskers (Q1 - 1.5*IQR and Q3 + 1.5*IQR)

Outliers (dots)

image source
Reading boxplots requires some experience and knowledge of data distribution. For more detailed information we recommend the article "Understanding Boxplots" by Michael Galarnyk: https://towardsdatascience.com/understanding-boxplots-5e2df7bcbd51

2.3 Availabilty Chart

2.3.1 Structure of the Availability Chart

The Availability Chart is a detailed tabular representation of the data of the Walter Lieth Climate Chart.

The location's name. A gazetteer is used to generate the name (https://www.geonames.org/). Alternatively, you can set a name manually.

The location's coordinates.

Elevation of the location. For this information, the gazetteer "Geonames" is used as well.

Köppen-Geiger Climate Class. (Markus Kottek, Jürgen Grieser, Christoph Beck, Bruno Rudolf and Franz Rubel. 2006. "World Map of the Köppen-Geiger climate classification updated." Meteorologische Zeitschrift 15 (3): 259-263. https://dx.doi.org/10.1127/0941-2948/2006/0130.)

2.3.2 Understanding the Availability Chart

The Availability Chart is an easy-to-understand instrument for displaying temperature and precipitation data as numerical values. The color-coding of the table cells allows you to quickly perceive the values. It allows the comparison of the monthly values over the selected time period. It is also possible to identify data gaps. These data gaps occur exclusively in the data set of the GHCN Weather Stations (see 1.3.1).

3 Download Charts

All charts of the application Climatecharts.net are available for free. In the upper right corner of each diagram you will find two buttons to save the charts as PNG file (raster graphics) or SVG file (vector graphics). Saving as a vector graphic also allows you to easily edit the data (e.g. coloring).

200 years ago there were less than one billion humans living on earth. Today, according to UN calculations there are over 7 billion of us.1 Recent estimates suggest that today's population size is roughly equivalent to 6.9% of the total number of people ever born.2 This is the most conspicuous fact about world population growth: for thousands of years, the population grew only slowly but in recent centuries, it has jumped dramatically.

Accuracy of the Time Zone Map

All clock changes worldwide are automatically taken into account and displayed in real-time as soon as you reload the page. Future changes are usually incorporated into our database before they take effect, so the map accurately reflects the current situation.

Please note that the Time Zone Map is not a political map but a time zone map showing the time zone boundaries.

How to Use the Map

Search for any city in the search field above and place a black "pin" by that city on the map. If you place more than one pin, an extra line of information is added underneath the map with links to those cities' pages. You may add as many pins as you like.

To remove the pins permanently (undo not possible), simply click here or on the Time Zone Map link in the menu above.

Hover your mouse over any of the red dots to see the name of the city and country and current local time.
"DST" is displayed if there is Daylight Saving Time at the moment.

Click on any red dot and go to that city's page with time, weather, sunrise/set, moon phases and lots more.

Hover your mouse over the map to highlight time zones.

Find the current time offset - displayed in whole hours only - from Coordinated Universal Time (UTC) at the bottom of the map. UTC offsets in diagonally striped areas are not whole hours.

Scenario

The available scenarios are in fact collections of numbers that describe celestial bodies and their position. These numbers are coming, for the most part, from Nasa's websites. Their accuracy is quite impressive, more than enough for the context of this simulation. The picture that you see on any given date represents what the real Solar System looked like on that date.

Date

The orbital elements of the planets are used to calculate their original position when picking a date. These calculations produce a very good approximation of the positions : you can compare the stars and constellations that you see in the background from other sources, provided that you place the point of view on The Earth.

Some scenarios are set to be animated by calculating positions from the orbital elements, but in some cases the velocity of each planet is derived from these calculations so that the positions are no longer calculated from the elements, but from the gravity that is acting between the different bodies. The calculation of these forces is also an approximation using a Quadratic integration, and its precision decays over time. This decay is more pronounced in some scenarios.

You can find on the internet the dates of celestial events, for example eclipses or lunar phases, and check if you can observe them in this simulation.

Please note that I use the Gregorian calendar for all dates, whereas Nasa use the Julian calendar for dates before the Gregorian reform (before 1582-10-15).

It is also worth noting that I use the ELP2000-85 theory to compute the Moon's position, which is not the exact same theory used by Nasa to compute its eclipse canon, so that there are small differences in the position of the Moon, particularly for very ancient dates.

Point of view

This option makes it possible to place the camera at the position of a planet of your choice, so you'd see the other planets from the point of view of the chosen one. From there you can zoom by scrolling.

The Free Camera is a camera that floats into space, and that you can move by scrolling and dragging. This camera always revolve around a point specified in the "look at" option field.

Look at

You can make your selected camera look at a planet of your choice, so that it always will be centered in your viewport.

If you place the camera from the viewpoint of a planet and look at another one, the latter's path will be traced relative to the former's position. This feature is useful to observe the apparent retrograde motion of the planets relative to the Earth.

Planet scale

When the scale is at 1x, the planets sizes are in 1:1 scale to the size of the orbits, and of the universe. Since the distances in the Solar System are so huge, we can't even see the planets at this scale, so I made it possible to make the planets larger to see them more easily. I left the possibility to view them at their real size, because I feel it gives a better hint about the vastness of our Solar System.

Speed

Move the slider to change animation speed. Depending on the scenario, precision of positions can decay with increased speed.

On an average day, there are roughly 90,000 commercial flights around the world. This stunning animated map displays them all in 4 seconds.

Every plane flight in the world over 24 hours

This incredible map was made way back in 2008 by Dr. Karl Rege of the Zurich School of Applied Sciences. Using arrival and departure data from the website FlightStats, he and his team simulated the flight path of every commercial flight over a 24 hour period and plotted them all in the map as tiny yellow dots.

The fact that they made the map back in 2008, when web mapping was still in its infancy, makes it all the more impressive. It also explains why such an impressive graphic never made the rounds on social media (in 2008, America's #1 social network was still Myspace).

You can view the original version of the map, which is quite a bit slower than the one above, on Youtube. The video file is also available for download on the University's website.

If you'd like to see some other work by the team, check out their " Blue Marble" video series, which is also very well done. The videos show a time lapse of the world's changing coastlines, starting 21,000 years ago during the last ice age and ending 1,000 years in the future.
My latest project is launching soon: Blueshift, a platform for designing and publishing dynamic maps for the web. If you'd like to give it a try, request a pre-launch invitation.

It's clear that the U.S. economy is heavily concentrated in certain locations (the Northeast, California, Chicago) and less in others (the Heartland and Mountain regions), but what is the precise distribution?

How much of the U.S. GDP comes from large cities versus rural areas? And how do the economies of each city compare with each other?

The distorted map below, known as a , is one way of approaching the question.

The GDP of every U.S. county

This map displays every county in the U.S. Each county is sized proportional to its share of the total U.S. GDP.

This map below highlights each of the 10 largest metro areas, along with its GDP.

To add some context to these numbers, Greater New York's GDP of $1.5 trillion is larger than all but 11 countries. If it were its own country, Greater New York's economy would rank just above Australia and South Korea and just below Canada and Russia.

At the low end of this group, Greater Atlanta's GDP of $325 billion is enough to rank it #36 on the list of countries, immediately below Denmark and Malaysia and above Singapore and Israel.

The shape of the UK economy

The last time I made a cartogram of the U.S., a number of people thought it would be interesting to see the same for the U.K., considering how much of its economy is concentrated in a single city, London.

So, for comparison, here is another cartogram showing how U.K.'s economy is distributed.

To see a cartogram breaking down the world economy by country, see: How We Share the World.

Sources:

All figures are quoted in nominal 2014 GDP.

The BEA publishes GDP for metro areas, but not for counties. To reach these estimates, I first calculated each county's share of U.S. aggregate household income. Then I grouped the counties together by metro area, and scaled them so that the sum of each metro area matched the BEA's figures.

From 1820 to 2013, 79 million people obtained lawful permanent resident status in the United States. The interactive map below visualizes all of them based on their prior country of residence. The brightness of a country corresponds to its total migration to the U.S. at the given time.

Two Centuries of U.S. Immigration (1 dot = 10,000 people)

Over time, the sources of immigration trace a clear path across the world.

Through most of the 1800's, immigration came predominantly from Western Europe (Ireland, Germany, the U.K.). Toward the end of the century, countries further east in Europe (Italy, Russia, Hungary) took over as the largest source of migration. Beginning in the early 1900's, most immigrants arrived from the Americas (Canada, Mexico). And the last few decades have seen a rise in migration from Asia. The same trends are clear looking at the history of New York City's foreign born population.

Here are the largest immigration "waves" charted over time, showing the progression.

While it may seem that immigration over the last few decades has been higher than ever before, the picture looks very different when viewed relative to the size of the U.S. population.

Here is the same chart, with the immigration shown as a percentage of the U.S. population.

Of my four grandparents, one is of Japanese descent, two are from Europe (a Polish Jew and an Italian Catholic), and one is native American. So genealogy and immigration flows have long been fascinations of mine.

What I think is particularly interesting about immigration to the U.S. is that each "wave" coming in from a particular country has a story behind it - usually escaping persecution (e.g. Jews escaping Russia after the May Laws were enacted, the Cuban Revolution) or major economic troubles (e.g. the Irish Potato Famine, the collapse of southern Italy after the Italian Unification).

There are plenty of dark spots on United States' history, but the role it has played as a sanctuary for troubled people across the world is a history I feel very proud to be a part of.

If you would like to read more about what caused each of these groups to come to the U.S., this graphic summarizes some of the major events.

Immigration: the new Godwin's Law

If you're not familiar with Godwin's law, it is an old internet adage that states, " As an online discussion grows longer, the probability of a comparison involving Nazism or Hitler approaches 1. "

Lately, I've found a similar principle applies to immigration. No matter what topic is being discussed online, if the conversation goes on for long enough, someone will inevitably tie it back to immigration.

Immigration has always been an important and frequently debated issue. And for many current events, the connection with immigration is clear, for example: terrorism / ISIS, the Brexit, Donald Trump and this year's presidential race, the refugee crisis. But at some point in the last year or two, I started noticing immigration being mentioned in connection with all sorts of topics I never would have expected.

To see what I mean, here are some of the topics I've posted about where immigration came up in discussion, either in the comment section of the post or on social media:

Why is immigration suddenly the cause / result / solution of everything? (Not meant rhetorically. If you have a good answer, I'd love to know.)

Who is migrating from where to where?

For a topic that comes up as often as immigration, I've found the debate to be really lacking in factual information. Hopefully this map is helpful is clearing up at least the simple, basic statistics: how many migrants are there? Where are they coming from? And where are they going?

Please keep in mind, these numbers are only estimates. You can find the full details of how they were calculated at the bottom of the post.

That said, here are a few of the pieces I found interesting.

Syria

Between 2010 and 2015, the net migration from Syria to Sweden was more than Syria's net migration to the rest of Europe and the Americas combined.

Many Middle Eastern countries have been criticized for allegedly accepting few Syrian refugees. In Qatar and the UAE, the net migration appears to actually be negative. Though of the Middle Eastern countries that are accepting Syrian refugees, the numbers they are dealing with are orders of magnitude higher than in the West.

The United Kingdom / Brexit

In the Brexit debate, the loudest arguments in favor of leaving the EU have been about immigration. What strikes me as interesting is how small a portion of the UK's net immigration is actually coming from Europe.

Australia

Australia, another country where immigration has become a highly charged political issue, jumps out as an interesting case.

By these estimates, Australia's net immigration is negative with every country in the world, except for a small positive immigration balance with Sudan. Australia is the only country in the world to have significant positive net immigration with the US.

United States

Last month, I posted a map visualizing 200 years of US immigration (inflows only). I would have liked to do the same with US emigration, which may be the more interesting direction since it is not nearly as well known. Unfortunately the US does not keep good emigration records and the best data I've managed to find goes back only a few decades. So, I don't foresee being able to make a historical US emigration map.

Still, I think it's pretty interesting to see what US net immigration flows look like in the present.

As mentioned above, according to these estimates, the US has significant positive net immigration with only one other country, Australia. The country with which the US has the largest negative net immigration is, perhaps unsurprisingly, Mexico. Though the amount by which Mexico leads is down substantially compared to a decade ago. Illegal immigration in particular has fallen off sharply, as demonstrated by this time series of border apprehensions from Pew Research.

When US immigration is viewed by region, the area that really stands out is Asia, which now accounts for just as much US immigration as North + South America (Mexico included).

Immigration between the US and Mexico is particularly complex, since it involves both legal and illegal immigration as well as temporary laborers, deportations, and a large number of people living in immigration detention facilities. For that reason, America's true net migration with Mexico is uncertain, and may actually be much lower than what's shown here. If you believe Pew's estimates, net migration with Mexico is now actually negative: more people are migrating from the US to Mexico than vice versa.

Immigration perceptions

Wherever you stand politically on immigration, you have to admit, it's pretty strange how rarely basic stats like these enter the debate. For all the discussion in the US about border fences and immigration limits, the simple question of "how many immigrants are there?" hardly ever even comes up.

Public opinion about immigration was likely a deciding factor in Britain's decision to exit the EU. And it may very well determine who becomes the next US president. Yet the majority of Brits and the majority of Americans misestimate the size of their country's immigrant population by a multiple.

The data for this map comes from the UN Population Division's estimates for Total Migrant Stock - the number of global migrants, broken down by country of residence and country of origin. The numbers are not fully consistent. In some cases, they represent foreign citizens and in others they represent foreign born. See the dataset itself for the full set of footnotes.

To convert those figures into immigration estimates, I took the difference between the migrant stock in 2015 and that in 2010. Since some of that difference is due to mortality, not immigration, I adjusted the 2010 numbers down assuming an annual mortality rate of 0.8%, the global average.

The map was made in Javascript using D3, three.js, and MapboxGL.

This interactive graphic shows how the world is divided according to six different socioeconomic variables. The land area of each country represents its share of the worldwide total.

Click on a circle to reshape the map

For attribution and data sources, scroll to the

I have been having fun experimenting with cartograms lately. As maps go, they have their shortcomings. But when it comes to communicating magnitude, I think they are much more effective than maps that do so with color alone.

For more information about what a cartogram is, have a look at my last two posts, The Housing Value of Every County in the U.S. and A Striking Perspective on New York City Property Values.

For this map, I looked at several different socioeconomic variables to include. I went with these six because I thought they each revealed something interesting about the world.

GDP

The GDP-scaled map makes it clear how dominant the U.S. economy is. The next closest country, China, has only about half the economic size, despite having a population four times as large.

Government Debt

Looking at the world scaled by government debt, the first thing that jumps out is Japan. Their national debt is 2.3 times as large as their GDP. The U.S. debt is small by comparison, roughly equal to the U.S. GDP.

Population / Births

Asia is home to about three fifths of world's population, and arguably the 10 largest human settlements in the world. On their own, China and India each have more people than Europe, Africa, or the Americas. However, the balance is shifting toward Africa, which is not far behind Asia in terms of annual births. According to a report by UNICEF, 40% of the world could be African by the end of the century.

Wealth

On the topic of inequality, most of the talk is about income, which is more or less represented by GDP. However, wealth is arguably a more relevant measure. Compared to the income gap, the wealth gap shows a more pronounced divide between developed and developing nations.

Extreme Wealth

The last variable, number of billionaires, was the one that surprised me most. 15 of the 20 richest people in the world are American, so I expected to see the U.S. dominate this category.

The U.S. has the highest number of billionaires, but relative to population size, it has fewer than either the U.K. or Germany. There are also many billionaires living in small Middle Eastern and fiscal paradise countries.

The Coriolis effect influences wind by deflecting its path to the right in the Northern Hemisphere. The sequence of weather satellite images shows that the actual wind direction is from the southwest. The satellite images show atmospheric motion over the northern Pacific Ocean for a 36-hour period.

Pendulums generally swing back and forth in a single plane fixed in space. On Earth however, if the path of a pendulum's swing is traced out over time, the orientation of the plane appears to change. This provides evidence for Earth's rotation because it shows that Earth is rotating underneath the unchanging orientation of the pendulum's swing.

You can click on the images of the planets to get more information about them from Bill Arnett's incredible Nine Planets web site.

WHAT IS GOING ON?

The Days (And Years) Of Our Lives

Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. This brings up the question of how we define the time intervals we measure. What is a day? What is a year?

The earth is in motion. Actually, several different motions all at once. There are two that specifically interest us. First, the earth rotates on its axis, like a spinning top. Second, the earth revolves around the sun, like a tetherball at the end of a string going around the center pole.

The top-like rotation of the earth on its axis is how we define the day. The time it takes the earth to rotate from noon until the next noon we define as one day. We further divide this period of time into 24 hours, each of which is divided into 60 minutes, each of which is broken into 60 seconds. There are no rules that govern the rotation rates of the planets, it all depends on how much "spin" was in the original material that went into forming each one. Giant Jupiter has lots of spin, turning once on its axis every 10 hours, while Venus takes 243 days to spin once.

The revolution of the earth around the sun is how we define the year. A year is the time it takes the earth to make one revolution - a little over 365 days.

We all learn in grade school that the planets move at differing rates around the sun. While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days. Poor, ponderous, and distant Pluto takes a whopping 248 years for one revolution. Below is a table with the rotation rates and revolution rates of all the planets.

Why the huge differences in periods? We need to go back to the time of Galileo, except that we're not going to look at his work, but rather at the work of one of his contemporaries, Johannes Kepler (1571-1630).

Johannes Kepler

Tycho Brahe

Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe. Tycho was a great and extremely accurate observer, but he did't have the mathematical capacity to analyze all of the data he collected. After Tycho's death in 1601, Kepler was able to obtain Tycho's observations. Tycho's observations of planetary motion were the most accurate of the time (before the invention of the telescope!). Using these observations, Kepler discovered that the planets do not move in circles, as 2000 years of "Natural Philosophy" had taught. He discovered that they move in ellipses. A ellipse is a sort of squashed circle with a short diameter (the "minor axis") and a longer diameter (the "major axis"). He found that the Sun was positioned at one "focus" of the ellipse (there are two "foci", both located on the major axis). He also found that when the planets were nearer the sun in their orbits, they move faster than when they were farther from the sun. Many years later, he discovered that the farther a planet was from the sun, on the average, the longer it took for that planet to make one complete revolution. These three laws, stated mathematically by Kepler, are known as "Kepler's Laws of Orbital Motion." Kepler's Laws are still used today to predict the motions of planets, comets, asteroids, stars, galaxies, and spacecraft.

Here you see a planet in a very elliptical orbit.
Note how it speeds up when it's near the Sun.

Kepler's third law is the one that interests us the most. It states precisely that the period of time a planet takes to go around the sun squared is proportional to the average distance from the sun cubed. Here's the formula:

Let's just solve for the period by taking the square root of both sides:

Note that as the distance of the planet from the sun is increased, the period, or time to make one orbit, will get longer. Kepler didn't know the reason for these laws, though he knew it had something to do with the Sun and its influence on the planets. That had to wait 50 years for Isaac Newton to discover the universal law of gravitation.

The Gravity Of The Situation

Isaac Newton

Closer planets revolve faster, more distant planets revolve slower. Why? The answer lies in how gravity works. The force of gravity is a measure of the pull between two bodies. This force depends on a few things. First, it depends on the mass of the sun and on the mass of the planet you are considering. The heavier the planet, the stronger the pull. If you double the planet's mass, gravity pulls twice as hard. On the other hand, the farther the planet is from the sun, the weaker the pull between the two. The force gets weaker quite rapidly. If you double the distance, the force is one-fourth. If you triple the separation, the force drops to one-ninth. Ten times the distance, one-hundredth the force. See the pattern? The force drops off with the square of the distance. If we put this into an equation it would look like this:

The two "M's" on top are the sun's mass and the planet's mass. The "r" below is the distance between the two. The masses are in the numerator because the force gets bigger if they get bigger. The distance is in the denominator because the force gets smaller when the distance gets bigger. Note that the force never becomes zero no matter how far you travel. Knowing this law helps you inderstand why the planets move faster when they are closer to the sun - they are pulled on with a stronger force and are whipped around faster!

Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass.

We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. The mass of a body is a measure of how much matter it contains. An object with mass has a quality called inertia. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again. If the stone is at rest, it wants to remain at rest. Once you've got it moving, it wants to stay moving. This quality or "sluggishness" of matter is its inertia. Mass is a measure of how much inertia an object displays.

Weight is an entirely different thing. Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the size of the masses and how far apart they are. For everyday-sized objects, this gravitational pull is vanishingly small, but the pull between a very large object, like the Earth, and another object, like you, can be easily measured. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight.

If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless. There is an anvil floating next to you. It's also weightless. Are you or the anvil mass-less? Absolutely not. If you grabbed the anvil and tried to shake it, you would have to push it to get it going and pull it to get it to stop. It still has inertia, and hence mass, yet it has no weight. See the difference?
