Week 4 [04.11-10.11.19] Dark matter

If you don't live in a big city in Poland, you can observe many stars at night. Did you ever wonder how would look our sky in the next millions of years if we would count only on existing proven astrophysical theories and calculations? It would be absolutely empty. All  celestial bodies  in the galaxy are rotating around the biggest black hole in the middle of galaxy (in Milky Way this black hole is 6.4  billion times heavier than our sun)  with such speed that the gravity generated by galaxy’s observable matter could not possibly hold them together. This leads us to  conviction   that something we cannot see is at work and is giving galaxies extra mass, generating the extra gravity that galaxies need to stay intact. Something, that will ensure us that our sky will remain the same as it was a million years ago. The official name of this strange and unknown matter is the “dark matter”. Unlike normal matter, dark matter does not interact with the electroma...

Week 4 [04.11-10.11.19] H.P. Lovecraft: the man who can make you feel afraid of seafood

As it has been Halloween period recently, it would still be appropriate to talk about something dark and spooky. I am not a big horror fan myself but I appreciate a good story with some eerie touch so that’s why I’d like for you to see a video about a horror author whose works are becoming more and more popular with each passing day, taking into account that he wrote them in the 1920s – 1940s. So, here are some questions for you: 1)       Are you familiar with H.P. Lovecraft’s universe? What is your opinion on his stories and their overall tone? 2)       In your opinion, what is the best platform for scaring someone — a movie screen, where all cinematic tricks are thrown at you, videogames, where on top of movie tricks you are in control of a character, therefore increasing immersion, or a book page, where it’s only a writer’s word, you and your imagination, face to face? 3)       What do you th...

Week 4 [04.11-10.11.19] Disney’s history

Talking about the biggest world corporations, one of the first ones that comes to your mind (at least it should) is The Walt Disney Company. Everyone has heard of it, everyone saw their cartoons or movies as a kid, not everyone has been to the Disneyland but I think many have dreamt of visiting one of them. I believe it is interesting to know how the great companies were founded and what their path to what they are now was so I decided to tell a short story about Walt Disney and the world he created. As a child, Walt Disney loved to draw and, as he stated later, he decided to become a cartoonist after the friend of his family, Dr. Sherwood, bought a picture of a horse that Walt drawn from him for 25 cents. Pursuing his dream, at the age of 22 Walt went to Hollywood where with the tremendous help of his older brother, Roy, in 1923 he founded the “Disney Brothers Cartoon Studio” as it was named at that time.       ...

Week 4 [04.11-10.11.19] What if you could trade a paperclip for a house?

Kyle MacDonald is a simple internet writer who lives in Canada. He allegedly "bought" him a house as a result of 14 trades which started from a red paperclip. How did he do that? Mr Kyle was living with his roommate, Dom(also means house in Polish), who didn't have a healthy income who was living an ordinary life just like many. As he was experiencing some financial problems, he started to think about the idea to save himself from this situation, and he came up with a game "bigger and better". The rule of the game was pretty simple, start with a small trashy object of your choice, using your intelligence and luck each time to trade it for a bigger and more valuable object. So if you play it well, you can have something bigger and more expensive within just a few trades. Kyle has developed this idea and started to game with a red paperclip and after only 14 exchanges he bought himself a house! How did he do? Here are the trades he done it well: 1)  ...

Week 4 [04.11-10.11.19] Do you always procrastinate? Read this before doing it again!

On the night of October 29, 1787, Mozart quickly entered to the stage of the Estates Theatre in Prague. He was so exciting. He stopped in the middle of the stage and greeted the audience. The crowd was even more excited. After all, they were going to listen for the first time to one of the most important works of this composer who had become a legend in his lifetime. Yes, maybe some of you might imagine, it was ''Don Giovanni.'' Estates Theatre  ( Source:  https://cdn-vsh.prague.eu/object/218/3.jpg ) At the premiere of such an important work, there were people who were even more excited than Mozart and those who came to listen to him: the orchestra members. Do you know why they were excited? Because they never rehearsed. They were about to practice the art while it's already happening. Because Mozart, who just entered the stage with quick steps, had just finished writing the notes of the overture which the audience is currently about to listen to. The...

Week 4 [04.11-10.11.19] What were the dinosaurs?

What were the dinosaurs? It is a good question. Almost everybody has seen the film "Jurassic World" which tells us the basic history of Jurassic and Cretaceous periods. There are many other interesting films and cartoons which describe this group of reptiles. However, in each film, they are represented in different ways. So, today, we will try to define what the dinosaurs actually were and how they survived in their days. For many years the scientists have been discussing what happened with our earth in the Cretaceous period and what happened with the dinosaurs. There are many theories about this but the main one is that an asteroid ended the reign of the dinosaurs. Another common cause why they became extinct is a massive climate change in pre-historic times. Nobody exactly knows, so we can only guess and propose how it was. Dinosaurs mostly lived on the eart h like Triceratops , Tyrannosaurus and Velociraptor . Tyrannosaurus https://www.syfy.com/sites/s...
