Learn One Thing A Day

The author ( C.G.P. Grey ) of this video is a very excellent science popularizer and this particular video makes you think... a lot! What the future will look like? Humans vs. (Ro)bots... Personally I still believe in human creativity and even if a world-wide poem and painting-based economy is unlikely to happen anytime soon, nevertheless it would be awesome :)

Hello internet! Here are four objects which come from NASA :) Thanks to SciShow Space for this very interesting video! Subscribe, it's totally worth it!

Have you ever wandered why do we draw Stars as Star-shaped objects instead, let's say, just dots? The short answer is ...  the light diffraction through small imperfections in our eyes. The long answer is ... provided by the beautiful video from MinutePhysics ... (totally worth to watch!!!)

Today I want to indicate you a couple of websites you may find very interesting especially if you would like to learn new things in your free time (yes why not?) Coursera Citing wikipedia Coursera is a for-profit educational technology company founded by computer science professors Andrew Ng and Daphne Koller from Stanford University that offers massive open online courses (MOOCs). Coursera works with universities to make some of their courses available online, and offers courses in physics, engineering, humanities, medicine, biology, social sciences, mathematics, business, computer science, and other subjects. As of April 2014, Coursera has 7.1 million users in 641 courses from 108 institutions. The website and the lectures and the hosted material (videos, assignment, lecture notes) are 100% free but in some cases a fee applies to get ( after the final passing of the exam ) an official certificate.

Today I want to talk you about milk! If you are an adult and you can still drink milk, well you and Wolverine have something in common, you are both mutants! In other ways, lactose intolerance is a normal thing. But let's go in order... Lactose intolerance is an impaired ability to digest lactose, a sugar found in milk and other dairy products. Lactose is normally broken down by an enzyme called lactase, which is produced by cells in the lining of the small intestine. Lactose intolerance in adulthood is caused by reduced production of lactase after infancy (lactase nonpersistence). If individuals with lactose intolerance consume lactose-containing dairy products, they may experience abdominal pain, bloating, flatulence, nausea, and diarrhea beginning 30 minutes to 2 hours later.... [ Genetic Home Reference ] Did you know that it is estimated that about 70% of adults worldwide show some decrease in lactase activity during adulthood? 70%!!! But also, did you ...

Today I want to talk about... (I have always wanted to use this meme :) )   People believing in aliens' existence, think of them as much more technologically and maybe physically than we are... but have you ever thought about the consequences if this were the case? The Italian Physicist Enrico Fermi (1901-1954) did and he defined what came to be known as the Fermi's paradox. ( Enrico Fermi , from wikipedia ) The story goes that, one day back on the 1940's, a group of atomic scientists, including the famous Enrico Fermi, were sitting around talking, when the subject turned to extraterrestrial life. Fermi is supposed to have then asked, "So? Where is everybody?" What he meant was: If there are all these billions of planets in the universe that are capable of supporting life, and millions of intelligent species out there, then how come none has visited earth? This the Fermi's Paradox . [Ref. 1] "Fermi realized that any civ...
