 Be Prolific

For example, Simonton cites the work of inventor Thomas Edison who accumulated a mind-boggling 2,300 patents over his lifetime. He found that in the same year Edison applied for patents for the light bulb and the telephone (certainly both hits) he also filed for patents for 100 or so other inventions including the pneumatic pen (a partial miss), a talking doll (a definite miss) and a ghost detection machine (enough said). In all likelihood, Edison never knowingly worked on something he thou...

 Physiological Effects from Exposure to a Vaccum

Vacuum doesn’t have a temperature of its own, so space is not really that cold. It’s a great insulator too, meaning that your core body heat doesn’t get sucked away. Without an atmosphere to transfer heat away, the risk of exposure is somewhat mitigated. The saliva on your tongue may boil off, as it’s not pressurized like your blood is, and you may get some frost on your skin. Sunburn from direct contact with the sun’s ultraviolet rays is a more immediate danger than perishing from ...

 Example of Relativity

Imagine that George, who is wearing a spacesuit with a small, red flashing light, is floating in the absolute darkness of completely empty space, far away from any planets, stars, or galaxies. From George's perspective, he is completely stationary, engulfed in the uniform, still blackness of the cosmos. Off in the distance, George catches sight of a tiny, green flashing light that appears to be coming closer and closer. Finally, it gets close enough for George to see that the light is attache...

 The Bell Jar

A famous experiment in high school physics involves putting an electric buzzer in a bell jar, a glass container from which the air can be removed by a pump. When the air is removed, the sound of the buzzer disappears. As early as the seventeenth century, it was recognized that sound needed some medium to travel in. In a vacuum, such as exists inside the bell jar, there is nothing to carry the sound waves, so you don't hear the buzzer inside. To be more specific, sound is a pressure wave, or d...
