Today I found out the first known robot was created around 400-350 BC by the mathematician Archytas and was an artificial bird. Archytas, who is known as the “father of mechanical engineering,” constructed his bird out of wood and used steam to power the movements of the robot.  This bird was then suspended from a pivot bar. In its best […]

Why You Used to Have to Use #2 Pencils With Scantron Forms

scantron

Today I found out why you used to have to use #2 pencils when using scantron forms. Now, you might be saying, “Used to? Don’t you still have to?”  It turns out, despite what pretty much all teachers will tell you, not really.  Modern scantron systems are quite high-tech, using image sensors and sophisticated image processing algorithms.  These algorithms can […]

Why It is Nearly Impossible to Tickle Yourself

tickling

Today I found out why it is nearly impossible to tickle yourself. It’s very hard to tickle yourself because your brain anticipates things going on around you in order to help speed up response times. More technically, the cerebellum monitors body movements and can also distinguish between expected sensations and unexpected ones, generally resulting in diminishing or completely discarding expected […]

Bananas Are Naturally Radioactive

banana radiation

Today I found out bananas are naturally radioactive.  This comes from the fact that they contain relatively high amounts of potassium.  Specifically, they contain Potassium-40, which is a radioactive isotope of potassium. The fact that bananas are radioactive has actually given rise to the radiation unit: “banana equivalent dose” (BED); this is the average amount of radiation you are exposed to by eating […]

What Causes Muscle Soreness After Exercising (Note: It’s Not Lactic Acid)

Muscle Cell

Today I found out what causes muscle soreness after workouts. Since the early 20th century, this specific type of muscle soreness, called “delayed onset muscle soreness” (DOMS), was thought to be cause by lactic acid buildup in the muscles during strenuous workouts where your body’s oxygen supply is depleted.  Recent research has shown this is not the case at all […]
