A moving bullet *does* lose force. Force can be expressed as the rate of change of momentum (F = mass*distance/time^2 = momentum / time = mass * velocity / time). If a bullet loses speed as it travels through the air, which it does, it loses force. » 3/25/15 9:05am 3/25/15 9:05am

Considering Gallagher was doing the same thing 40 years ago with watermelons, it's entertainment. It is not necessary for everything to have a deep subtextual meaning: Nobody has believed otherwise since Freud and his psychological subtext debacle. » 3/20/15 2:11pm 3/20/15 2:11pm

Magnetic fields quickly drop off as you get away from the source. The MRI machine in my hospital generates a field of 1.5 Tesla, about a million times stronger than the Earth's. However, beyond 15 feet a compass isnt affected. » 3/20/15 10:03am 3/20/15 10:03am

No, the aggregate beam is only harmless up to a certain point. My rough estimate of the collector array surface area is 75,000 m^2. At a megawatt scale the incoming energy flux is probably too low to be harmful. But at a gigawatt scale the energy flux could be damaging. » 3/14/15 9:05pm 3/14/15 9:05pm

High quality equipment still exists, but the first of whatever you own usually is inexpensive and low quality. Hopefully once you start replacing your stuff, you got money saved up and/or a better paying job to get high quality. Unfortunately in modern America the cost of living has quickly outpaced the dwindling… » 3/07/15 9:40pm 3/07/15 9:40pm

You talk as if "the grid" was designed by one overseer. It wasnt. A electrical power network is very haphazardly produced as demanded. Government interference by replacing consistent, reliable inconsistent, unreliable power sources will be an overall detriment. Supplementing with wind and solar isnt bad but replacing… » 2/24/15 7:10pm 2/24/15 7:10pm

You cant just jump to stay stationary on a tredmill. Lets examine from starting stationary in the air falling to the ground. When you land you are in contact with the treadmill for some definite amount of time before you jump into the air; Thus the treadmill will impart some amount of backwards force on you.… » 2/18/15 8:30am 2/18/15 8:30am

VSauce gets it wrong; The thing is, neutronium can only exist in a neutron star; It takes a LOT of gravity to compact matter that dense. Any small amount of neutronium outside of a neutron star wouldn't have enough gravity to keep it compacted, and would immediately explode. It would be a very, very, very big… » 3/21/14 4:21pm 3/21/14 4:21pm

It has to do with intent behind those figures; It's really the same thing with characters in video games: A half naked muscular male character represents what male players want to be (and what male industry leaders want them to want) and a half naked female character represents not what female players want to be, but… » 3/07/14 9:08pm 3/07/14 9:08pm

Typically, inefficiency with electronics means a lot of power is lost in the machine as useless heat. But that's exactly what a dryer is meant to do: generate heat. Saying a dryer is inefficient is missing the point of what a dryer is supposed to do. » 3/05/14 1:05pm 3/05/14 1:05pm
