Are we made of waves? Radio waves are obviously waves. Only when we come close do we notice that this object is actually a wave. Summary: With quantum theory, we find a beautiful unification: instead of there being two fundamental entities (particles and waves), there is only one fundamental entity: waves. Does Matter diffract? All […]

Why is a burette more accurate?
Why is a burette more accurate? Burettes are larger than a pipette, it has a stopcock at the bottom to control the release of liquid. Burette is similar like graduated cylinder and is easier to measure a required volume of liquid through graduations. But, it has large meniscus and hence its accuracy and precision is […]

What are long waves?
What are long waves? Long waves, also called infragravity waves, have a wave period of 30 seconds to several minutes. Astronomical tides represent one important example of long waves. Long waves can occur in shallow water, such as the Chesapeake Bay. But long waves are not limited to what is normally considered shallow water. What […]
Which gun has the most recoil?
Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]
