Space edition: Earth without the Moon and the Mars Space Exploration Vehicle

Without the Moon we would have a short day, since the planet would spin faster. A day would be only 6 hours long. Also, without the Moon the tilt of Earth would vary so much that seasons would be wildly inconsistent from year to year. So, the Moon is very important. Also, in this space […]

The particle zoo of 400 or so subatomic particles

Via Wikipedia: In particle physics, the term particle zoo[1][2] is used colloquially to describe a relatively extensive list of the then known “elementary particles” that almost look like hundreds of species in the zoo. In the history of particle physics, the situation was particularly confusing in the late 1960s. Before the discovery of quarks, hundreds […]

What and how: fruits/vegetables and diverting an asteroid

What is the difference between a fruit and a vegetable? You call it a fruit when the part that you eat stemmed from the flower of the plant, then grew around some seeds. This way cucumber, peas, apples, pears and tomatoes are fruits. But what about vegetables? If you eat the root, the leaves or […]
