What are windows (and some cups made out of)? The answer is glass. Glass is made by heating sand to the point where it melts and forms glass that can be shaped if it is hot enough. We still use glass everyday and it was a very important discovery for mankind.

Cats are animals that started to be seen more in the time of the Romans. Just like we have cats today, the Romans had them as pets.

A question that I always had before taking this class was; How did people know what day it was before there were clocks and phones? That question was answered when I learned that the Romans actually came up with calendars that are very similar to the ones that we use today.

Why would you spend money making two separate spoons and forks and waste precious space holding them when you can just combine them? That was probably the exact thought process of the Romans when they invented "Sporks". Nowadays, we mainly just stick with our spoons and forks but sporks still exist and they can be found in many restaurants.

So that society could stay under control better, laws were created that every Roman had to follow. These laws created a more orderly society but also created the opportunity for people to rebel by not following the laws (which is why they created the police). We still have laws today that all of the public have to follow or face consequences for not doing so.

After the Romans came up with laws, they learned that not all of the citizens would be happy with it and follow them. As an effect of this, a force was needed to make those who did not want to follow the law, follow the law so that is why they created the job for policemen that is still critical in our society today.

At the time of the Romans, wine was used because water was not always purified but the alcohol in the wine made sure that the wine was which made it safer for them to drink. Nowadays, wine is a beverage drunk by people 21+ mainly for the taste.

Swords were given to gladiators and soldiers to fight with. We do not use swords that much anymore because of all of the new technologies (i.e. guns) but we still know their historical significance and value ancient swords because they are important artifacts that give insight into the Roman world.

Concrete / Cement was and still is used in the construction of almost all of the buildings around us. Without concrete / cement we would not have many buildings that we have today and the Romans would not have either.

Aqueducts were used back in the time of the Romans to carry fresh water through mountains to residential areas. Nowadays, aqueducts are considered to be any system of pipes, canals, ditches, etc...

They had central heating, baths with all the commodities and bridges and roads that are still functional even after two millennia. The Colosseum could have resisted in perfect state if it had not been plundered. All was made of stone, timber and concrete. From Iraq to Portugal and from Sahara to Romania, Germany and UK, the Romans still impress us with their buildings of cement, stone and bricks. The Romans' greatest discovery was the concrete.

One of the most impressive pieces of Roman architecture were the aqueducts. In Spain, Roman aqueducts were still used during the 19th century. Medieval Arabs copied the Roman architecture of the aqueducts.

Roman aqueducts brought water into the ancient cities. But their role went even further, as a symbol of Roman engineering, an item of standing, social prestige and luxury. Not the aqueduct made the city, but the city could afford an aqueduct. The reasons for making the aqueducts were the same that made the cities build forums, thermal baths, amphitheaters and circuses. An aqueduct was a reason of proud for the city dwellers.

Still, the Roman aqueducts represent a formidable technological progress. The inhabitants of the Roman cities had at their disposal a daily water amount 10 to 20 times bigger than the city dwellers of the Europe of the 19th century, who consumed about 25-50 liters of water each day.

During the Rome of the emperor Trajan (98-117 AD), each inhabitant of Rome could use, at least theoretically, 1,000 liters of water daily, which is twice more than a French inhabitant in 1987! And Rome was not the only example: four aqueducts could deliver to Lyon 80,000 cubic meters of water daily, while just one aqueduct delivered 37,400 cubic meters of water each day to a neighboring city. All this water served both for public and individual needs.

In Pompeii, few particulars installed current water in the house. Instead, plenty of water flowed in the public wells, draining from the streets into a sewage system that ensured cleanliness of the city.

The Romans contributed lots of inventions to those around them. Some of them we still use to this day. Some examples of Roman contributions are :
