We all have the almost instinctive ability to tell the difference between a wet and dry surface. Knowing that dark spots on clothes, blackboards, sand, roads and many other things usually indicate these to be wet spots. On top of that it also makes some materials more translucent, just think of a wet shirt.
The question that arises from all these observations is;
If you ask anyone for a description of snow, you would most likely hear them say "white". In fact, this is so embedded in our perception of the world, that it is a mere fact for most. However, when one stops to think about it, he soon discovers that it isn't that obvious or straightforward at all. So why is snow white?
When we look
Earlier this week NASA released images and videos of a massive coronal mass ejection(CME), which was recorded by the Solar Dynamics Observatory (SDO).
During this enormous eruption a huge amount of solar plasma (primarily consisting of protons and electrons, but also having some heavier elements up to iron) was flung out of the sun at a velocity of about 1450 km/s.
If this event would have
Everyone has seen a few balloons in his lifetime, whether they are helium or air filled. If this is true for you, than you probably have noticed that balloons filled with Helium float high into the sky, while the ones filled with air drop to the ground. You may also have wondered why this is the case, and what about hot air balloons?
We at trulyscience are proud to announce that we have launched our very own Ambigram Generator.
Dating back several years, this generator is one of the first of its kind. And even though it now vastly outpreformed by its newer generation counterparts, it still is a fun tool to play with and definitely something that we want to keep around.
We are planning an update eventually,
