3-Day Weather Report

Graph of the Weather Report at Elysium Planitia

This plot is being updated daily throughout the duration of the InSight mission. The plot shows the latest three sols (Martian days) of weather data at InSight's landing site near the equator of Mars. Time runs along the bottom of the plot with the most recent data at the right. Numbers along the bottom show hours of local time at the InSight lander (Local True Solar Time, based on Sun angle). Lighter and darker vertical bands indicate daytime and nighttime at the lander, respectively. The corresponding Earth time is also shown at the top of the plot, in Coordinated Universal Time (UTC). All data points are one-hour averages of the calibrated data from the spacecraft.

Temperature Plot (not currently being generated):
Air temperature is shown in degrees Celsius, as measured by the Temperature and Wind for InSight (TWINS) instrument.

Pressure Plot:
Atmospheric pressure is shown in Pascals, as measured by an air pressure sensor, which is part of the Auxiliary Payload Sensor Suite (APSS). Typical sea-level pressure on Earth is around 101,325 Pascals (1013.25 hPa).

Wind Plot (not currently being generated):
Wind speed is shown in meters per second, as measured by the pair of TWINS booms. The barbs extending from each wind speed data point indicate the compass direction of the wind (e.g., a wind blowing from the north will have a barb straight up above the point; a wind blowing from the west will have a barb off to the left). Full and half flags extending from the barbs indicate the wind speed, with each half flag representing approximately 2.5 meters per second. A circle in place of a barb indicates a wind speed less than 2.5 meters per second.

Seasonal Weather Report

Seasonal Change Since InSight's Landing

This graph illustrates seasonal change in Elysium Planitia since InSight landed. The five datasets on this graph give a full picture of what it might be like to spend a year near the equator on Mars.

The Earth months run along the top of the graph.

The number of days (or sols, on Mars) runs along the bottom of the graph with the most recent day at the right

The vertical columns of color denote the seasons on Mars

Air Temperature: The black line shows the daily average air temperature in Celsius. Each sol's maximum and minimum air temperatures are at the top and bottom of the vertical grey bar.
Pressure: The black line shows the daily average atmospheric pressure in Pascals at the InSight site, along with each sol's maximum and minimum pressure on the grey bar.

Wind Speed: The black line shows the daily average wind speed in meters per second at the InSight site. The grey bars show each sol's maximum and the 90th percentile lowest winds as measured by the wind sensors.

Wind Direction: The black dots show the daily average wind direction depicted in degrees east of north, as if reading a compass. East is at 90 degrees, South at 180 degrees, west at 270 and north is 360.

Atmospheric Opacity (or tau): This is a measurement of how much sunlight is blocked by dust in the atmosphere before it reaches the ground. The green triangles are measurements (with gray shaded error bars) of tau taken by the Instrument Deployment Camera (IDC) on the robotic arm. Blue triangles are measurements made with the Instrument Context Camera (ICC), mounted below InSight's top deck.

Megacities visualized using population data for every 1,000,000 square meters.

This is a story about how to perceive the population of cities.

If we zoom out to view the entire world, it looks different than you might expect.

From my perspective (albeit a US-centric one), it was eye-opening to see how the world's population is so unevenly distributed. For example, compare the West Coast of the United States to Java, an island in Indonesia (home to 140 million people).

Regions at Comparable Scale

What stands out is each city's form, a unique mountain that might be like the steep peaks of lower Manhattan or the sprawling hills of suburban Atlanta. When I first saw a city in 3D, I had a feel for its population size that I had never experienced before.

That feeling goes a long way to improve my own geographic instincts. In 1993, there were 14 cities with over 10 million people. Today, 20 additional cities qualify (and another 11 will by 2030), with many sprouting from farmland in our lifetimes. Unless you've visited one of these new cities of 10 million people or tracked its growth closely, its scale can be hard to envision.

Among them is Kinshasa, Democratic Republic of Congo (13.1 million people), which I now know to be bigger than historically populous cities (see my article on Kinshasa's airports vs. other cities'). I saw it outrank Paris (11 million people) in population bar charts and data tables. Yet it wasn't until I saw the population as a form, rather than a number, that I could appreciate how large Kinshasa had become.

The 3D view left me with a better understanding of the world's center of "human" mass, especially the weight of Africa and Asia. First, let's tour a few cities, giving you a sense of what 10 million people "looks like."

This project wields data from the Global Human Settlement Layer, which uses "satellite imagery, census data, and volunteered geographic information" to create population density maps.

In parts of the world where census data is unreliable (e.g., India, China), population density was visibly noisy on the maps.

Using this data for research purposes has a number of caveats, and most are very well detailed in this paper in the Journal of Maps by Duncan Smith.

The data is processed using Google Earth Engine (example script is here).

The visualization was inspired by Alasdair Rae's blog posts, where he explained how to visualize snapshots of the data.

A more detailed explanation of the data processing is here.

They are used in many areas of life where we need to categorize or group items, as well as compare and contrast different items.

In this post we will take a look at several real world uses of Venn Diagrams and Set Theory.

When we use eBay or any other shopping search engines, set theory is involved.

If systems like eBay stored all of their items in one giant database set, then it would take much longer than a couple of seconds to get a response to our search query.

What these computer systems do is split up their data into several separate sets, such as all of the Products for Australia, all the cars for Australia, all of the Toyota Cars for Australia, and so on.

When we do the search query shown above, the eBay computer searches its database and finds the intersection or "join" of two sets:

Toyota Cars which are Landcruiser models

and

Toyota Cars which have a price Between $20000 and $40000

This enables the search results to be obtained and displayed very quicky.

This type of processing involves use of Database Tables and "SQL" Structured Query Language, that uses AND, OR, and NOT statements to do set theory operations on the data.

Understanding Venn Diagrams and Set Theory is crucial for anyone wanting to work as a Computer Programmer or Database Administrator.

In the remainder of this lesson, there are plenty of real world Venn Diagrams that we found by Googling the web.

As you will see, Venn Diagrams are used in the Sciences, in Languages, in Social Studies, in Economics, and also sometimes just for fun.

If a diagram is too small to see, then click on it to go full size. You may then have to use the browser back button to return to this page.

Venn Diagrams are used in Language to make detailed analysis and comparisons.

The following Venn Diagram shows types of English words that are different in spelling and meanings.

Diagrams can also be used when studying literature to compare the content of novels.

Venn Diagrams can also be used to compare characters in a novel.

They can also be used to critique the works of all the Authors a person has been reading.

Venn Diagrams can be used to show the relationships in complex organizations such as the European Economic Union.

Diagrams can also be used in Geography to explain how nation groups and states belong to each other. (Click on this image to make it fully visible).

Here is a diagram which shows the relationship between Solids and Liquids.

Venn diagrams can be used to list all the issues associated with environmental and economic concerns.

Venn Diagrams are used in Psychology.

Venn Diagrams can be used to show the changing nature of work in our world.

Diagrams can also be used by Human Resource Managers and Careers Advisors to show the characteristics of different jobs.

Venn Diagrams can be used for analysing the effectiveness of websites.

Venn Diagrams are used in Politics to describe types of government systems.

This one shows a Comparison Between Responsibilities of American State and Federal Governments.

Venn Diagrams are used by Geologists and Mining Engineers for mineral exploration.

Venn Diagrams are used a lot in modern Marketing Analysis.

Venn Diagrams are used in Mathematics to divide all possible number types into groups.

They are also used in Mathematics to see what groups of numbers have things in common.

Venn Diagrams can even be used to analyse music.

We can analyse the characters in TV shows like "The Muppets" with a Venn Diagram.

Some people even use Venn Diagrams to make jokes about Venn Diagrams.

And some people just make funny Venn Diagrams for humorous purposes.

The following Venn diagram was made by someone who has obviously used a lot of Public Toilets.

The following diagram summarizes my own experiences of Airline seating perfectly.

Surprising Venn Diagrams

# data[].attributes.attachment_link.readable_text
John Venn, the inventor of the Venn diagram, was born 180 years ago today. Here are 21 surprising things you can use Venn diagrams to describe.

John Venn was an English logician who was famous for inventing the Venn diagram, a graphical illustration which can be used to describe relationships in data.

A Venn diagram has overlapping regions which describe what the object or "set" would be if it had all the overlapping traits.

For instance, number two in this list has all the ingredients of a pancake, and the overlapping areas show what they would be if they were combined.

They're very useful to describe logical relationships, and they can be quite funny too.

Here are 21 surprising things you can describe with a Venn diagram:

1. John Venn

2. How to make pancakes

3. Helicopters in movies

Photo: Kind of normal

4. Steve Miller Band's classic song "Joker"

Created by George Anders.

5. Trousers (pants for yanks)

6. Daft Punk's Get Lucky

Photo: UsVsTh3m

7. Nuclear targets

Like Walderslade in Kent which was in the middle of three Soviet ICBM missile targets in the 1970s.

8. Hipsters

Photo: The Meta Picture

9. Eurovision songs

10. Relationships

11. Body image

12. A platypus playing a keytar

13. Embarrassing things on Google

Things that Google is having to delete after a European court ruling.

14. The feeling of having voted

That smug feeling on election day.

15. People who don't understand Venn diagrams

(This one's a joke.)

16. Different plant species

17. The Armstrongs

Photo: Kind of normal

18. EU foreign policy

19. Father Christmas

20. Similarities between unicorns and narwhals

21. ...and finally: how to make a Venn diagram

Iteration

When designing algorithms, there may be some steps that need repeating. This is known as iteration, and can be displayed in pseudocode or flowcharts.

Iteration in algorithms

An algorithm is a plan, a set of step-by-step instructions to solve a problem. There are three basic building blocks (constructs) to use when designing algorithms:

sequencing

selection

iteration

These building blocks help to describe solutions in a form ready for programming.

What is iteration?

An explanation of iteration, as used in algorithms and programming

Transcript Download Transcript

Iteration in programming means repeating steps, or instructions, over and over again. This is often called a ‘loop’.

Algorithms consist of instructions that are carried out (performed) one after another. Sometimes an algorithm needs to repeat certain steps until told to stop or until a particular condition has been met.

Iteration is the process of repeating steps.

For example, a very simple algorithm for eating breakfast cereal might consist of these steps:

put cereal in bowl

add milk to cereal

spoon cereal and milk into mouth

repeat step 3 until all cereal and milk is eaten

rinse bowl and spoon

Why is iteration important?

Iteration allows algorithms to be simplified by stating that certain steps will repeat until told otherwise. This makes designing algorithms quicker and simpler because they don’t need to include lots of unnecessary steps.
