The Epic of Gilgamesh
Human civilizations leave behind architectural masterpieces, creating a mysteries to us until today. Manuscripts are one of the rare pieces and the most difficult to preserve, considering they were written on wall or clay boards. Most civilizations left literary scripts reflected the civilizations intellectually and socially. The Epic of Gilgamesh is a Sumerian epic poem, written on 11 clay tablets, narrating a half human half god, named Gilgamesh, king of Uruk. This epic poem received great attention for the significance of Mesopotamia and its witnessed impact on other civilizations. The significance of this epic poem relies in being an ancient literary work.Continue Reading »

Inside the Minds of Hyperpolyglots
Language plays the primary role in organizing, classifying and storing thoughts and constructing knowledge. It is the window of a person as seen by others, the reflection of one’s thoughts and mood, and that source of the various sciences of human and nature. In this article, we will talk about people who have the extraordinary ability to learn many languages; otherwise known as Hyperpolyglots.  Unlike what the common notion states, that languages are acquired at an early age, Darwin tells us that it is in fact an “instinct to acquire an art”. However, instincts are defined as the natural reactionsContinue Reading »

Where Do Deleted Files Go?
Ever wondered what happens to deleted files? Or where do they go? Ever heard from a friend that all your photos and personal files could be restored from your phone or computer even if you wiped it clean or formatted it? Ever been in a situation where you had to restore files from your laptop after formatting it, and it failed?! In this article we’re going to explain how computer files get stored, deleted and restored. When a file is deleted from a hard drive or any other storage media, it’s not actually erased. In fact, small information that pointsContinue Reading »

Photosynthesis
This article talks about the source of all life on this earth, the process of photosynthesis. We all owe our lives to this process. In fact, more than 99% of earth’s productivity is nothing but photosynthesis. What are organisms but a collection of intricate and complex biochemicals that interact in quite a marvellous way. In order to stay alive, all living organisms need to constantly use energy. In other words, those chemicals need energy to be added constantly in order to keep reacting. However, the first law of thermodynamics states that “energy cannot be created nor destroyed, it can onlyContinue Reading »

Space Junk
Today on T3rf De we visit space again. We will talk about a problem that space engineers and scientists face whenever they try to send something to space, and we will talk about a solution that many others are proposing. The problem is space junk and the solution is a janitor. Please help us by sharing this article on Twitter and Facebook. Also, don’t forget to add your email on our mailing list on your right hand side. Decades since humans sent the first object to orbit Earth, Sputnik, we sent many satellites and manned-missions in orbit; most notably, theContinue Reading »

Europa
Today is our first year anniversary! T3rf De is one year old; young and strong! Without your support we would not have made it. As a special thanks, we bring you the latest update on Galileo’s- the spacecraft- newest updates! Galileo has been gazing and measuring Europa for a while. Here, when we say Europa, we do not mean the Old Continent. We actually mean Europa, one of Jupiter’s moons.

The Sun
The Sun, the brightest object in the sky. The energy source for life on earth. Our star. We wrote an article about the life and death of stars. Reading that article tells us that the Sun is classified as a type G star; a yellow dwarf. In our attempt to write about the Sun, we found a problem in which interesting facts we should include as they are plenty. We simply opted to stick to facts that can be related to our previous articles.  As usual, please help us by sharing this article on Twitter and Facebook. Just as theContinue Reading »

Discipline in Children
After a short break (to us, it was a very long one) we will start posting regularly again. This week we will talk about discipline in children through sports. We touch on definitions of discipline, it’s importance and try to connect to football (soccer for our American friends). The writer of our article today is our guest Miss Mai Abdulsalam. And as usual, help us by sharing the article on Twitter and Facebook. Discipline in children is something that people don’t take seriously in our societies; unlike concept of discipline in educational and professional circles. It can become a cultureContinue Reading »

Can a human survive space
We try to briefly answer the possibility of having people surviving in space without equipment. Logically, the straight answer is no. We try to explain why and for how long? Help us by sharing this article on Twitter and Facebook. A human can survive is space but for only minutes. Space is very cold, in reality it is -270 degrees. has almost no air, which means there is no pressure. Meaning if a person was exposed to space, he will freeze almost instantly soft tissue water will evaporate and that in his blood will start form bubbles. Water in human body willContinue Reading »

Internet Security
Today we will talk about our data moving around on the internet. How does Internet security works? Can we be sure that our money won’t be stolen from our bank accounts? How about our email content? Other services? A lot of us feel that those services are safe; others not so much. Today’s article is written bey Ahmed Al-Okor; an IT expert. Help us by sharing this article on Twitter and Facebook Is my connection really secure? Can my identity be revealed on the internet even if I’m using VPN or on an SSL link? To answer this question, weContinue Reading »

Life and Death of Stars
After a two week break, #T3rfDe returns to you with an article that talks about the life and death of stars. Stars here do not mean Frank Sinatra and Pat Benatar. Rather, stars in the sky; including the sun. We suggest to read our previous article about nuclear reactions before continuing this article. Don’t forget to help us by sharing this article on Twitter and Facebook. All around the universes and inside galaxies are gas clouds. Massive gas clouds that can reach up to the size of several solar systems, and they are made primarily of hydrogen and helium, alongContinue Reading »

The Milgram Experiment
No, not the milligram experiment, Stanley Milgram (with one L) was the social psychological researcher who preformed the experiment we will discuss today and analysed its implications on the human psyche and behaviour. Don’t forget to share the article on Twitter and Facebook. The Milgram experiment tests how far a person is willing to obey a figure of authority. There are a few versions of the experiment. We will stick to the one that goes as follows. We have three people: A scientist (the person giving orders; he’s part of the experiment) A teacher (tests the learner and punishes him;Continue Reading »

The Argument From Ignorance
Today we complete our series about logical fallacies. It is indeed not an inclusive series. However, we tried to simplify commonly used ones. We hope you enjoyed reading them. If you did, follow us on Twitter and Facebook. Is there life on other planets? Is there a way to prove it? We can’t be sure if yes or no only because science hasn’t discovered it yet. Now, was Steve Jobs some space traveller who came to earth to teach us about new technology? Can you prove otherwise? (hint: he’s born 1955). The difference between the two questions is clear. WeContinue Reading »

The Misinformation Effect
Today’s article talks about an effect that happens within the human brain. This effect is called the misinformation effect. It affects how our memories work. Don’t forget to follow us on Twitter and Facebook. Popular belief says that we replay our memories like a movie. Nothing could be further from the truth. Every time you remember something, you build up your memory from scratch. Which makes memory permeable to your present self’s influence! Memory is not like a movie you replay. It’s more like pieces of Lego you build. Let us imagine the following scenario. You are in a highContinue Reading »

The Strawman Fallacy
Today we present to you the second part of the logical fallacies series after the Texas Sharpshooter Fallacy. Today’s article speaks about a fallacy that many people fall into in a daily basis. When people argue they try their best to only use facts and try their best not to stray away from them. However, as it happens, they sometimes reframe their opposition’s view to something hypothetical and, sometimes, fictitious. By doing so, they’re sidetracking the argument and forcing their opponent to defend something they’re not suggesting nor defending. This artificial stance they’re creating for their opponent is what’s calledContinue Reading »

The Goiania Accident
This the second part (First Part here) of an article trio where are discussing three scientific disasters mainly caused by ignorance and slow bureaucratic decision taking. We will discuss the Goiania accident which took place in Brazil in 1987. Radiation is routinely used in medicine for treatment, usually in cancer therapy, or in the food industry to sterilise food. Thus, many large hospitals and institutes around the world have equipment for radiation therapy. In 1985 The Instituto Goiâno de Radioterapia, in the city of Goiania in Brazil, moved its building to a new location and left a 1977 radio therapy machineContinue Reading »

Global Warming
Today, March 23rd, is Earth Hour day, whose goal is to raise awareness regarding global warming. Today’s article, written by Nour Fitiany, our own environmental warrior, introduces the concept of global warming. Contrary to popular belief, global warming, or the increased temperature of the globe, is actually a natural occurrence. The Earth has natural periods of warming and cooling. In fact, the Earth is now 5° hotter than it was 10,000 years ago. The issue today is the rate at which the temperature is rising. The Earth’s temperature has risen 0.7°c in just the past 50 years (now let’s takeContinue Reading »

Voyager and The Golden Record
Today’s article on T3rf De talks about how far from Earth we’ve been able to travel, and how far we’ve gone. ________________________________________________ Update: Three days after publishing of this article, Nasa has announced that Voyager has entered a new area of space. This has sparked controversy in the astronomical community regarding whether or not Voyager 1 has actually left the solar system. Nasa announced that the newly discovered region has significantly higher levels of cosmic radiation, an indication of interstellar space. Voyager 1, however, is still under the effect of the Sun. The mission team expect this to be the last regionContinue Reading »

What’s up with 0s and 1s?
Once we see a series of 0s and 1s we immediately think of computers. T3rf De will dedicate this week’s article to an introduction to what those 0s and 1s mean and how are they interpreted. There are two modes to a basic electric signal, either on or off. People have been using these two modes of electric signals since the 1800s through the usage of telegraphs. Based on this, if a signal is on, it is assigned the number 1, and if it’s off, it is assigned the number 0. As an example, think of your computer or TV,Continue Reading »

Zimbardo Prison Experiment
Today’s article on T3rf De introduces the Philip Zimbardo experiment, in which he simulated a prison environment at Stanford University, producing unexpected results. Help us by sharing this article on Twitter and Facebook. Dr. Phillip K. Zimbardo, a professor of psychology at Stanford University, had devised an experiment to see the effects that roles have on average people when these roles are required of them. In his experiment, he took 24, predominantly middle-class, volunteers, intentionally excluded anyone with a criminal record or potential for violence. The volunteers were placed in a basement, which had been converted into a “make believe”Continue Reading »

Prince of Mathematics: Gauss
When someone refers to Mathematics to be “the queen of sciences” then that person must be the prince. Today we talk about Carl Friedrich Gauss. Help us by sharing this article on Twitter and Facebook. Carl Friedrich Gauss (1777-1855) was a German Mathematician and physical scientist. Having revolutionized math in his own way, some mathematics historians considered him as one of the three pillars of modern math (the other two being Archimedes and Newton). Gauss’ contributions go from number theory to astronomy passing through electrostatics and statistics. In the next few paragraphs we will try to  introduce some of hisContinue Reading »

Our Maps are Wrong
The art and science of map making may be harder than it first appears We all use Google Maps on a regular basis. But what if I told you that Google Maps are wrong. Don’t believe me? Then let me give you a quick example (and you can check it yourself if you don’t believe me). Above is a screenshot of Google Maps world view. Now, we all remember from our 4th grade geography class that Africa is the world’s 2nd largest continent. Now look at Greenland, and compare. It’s about the same size as Africa, and about 10 timesContinue Reading »

Why The World Won’t End Today 21/12/12
Today’s article is about the “End of The World” myth, which has been associated with today. Where it comes from and why it’s wrong. Before I go on to explain all the different reasons why the world won’t end today, I’ll first need to explain why people think the world is going to end in the first place. It all to do with the Mayans. The Mayans were a civilization which mostly thrived in Mesoamerica in the period between 250-900 C.E. (They were around long before this, but we’re really focusing on the previously mentioned period). The Mayans were aContinue Reading »
