Technically, we all have the capability for what could be described as "superhuman" hearing, sight, and smell. A healthy young adult can see a candle flame from 30 miles away. We can detect a smell when just 30 molecules of certain substances are present. So why don't we feel like our senses are super strong? According to neuroscientist Bradley Voytek, it's because we aren't paying enough attention. Basically, what we can sense under optimal conditions doesn't reflect what we do sense in the busy, distracting, real world.
Don't try this. Dianna from Physics Girl showed how under highly controlled conditions it's possible to dip one's hand into boiling oil without injury. The video is unlisted and age-restricted to keep children and dummies from trying to replicate the physics demonstration that's often done with molten metal.

If you've never heard of MATLAB or think it sounds vaguely like certain TV shows from the '80s, you'd be forgiven. Because even in a tech sector chock full of intricate, complex programs and systems that routinely leave lay people scratching their heads, MATLAB is science tech for the serious, SERIOUS scientists. Since its humble… READ THE REST
