Does Your Brain Take Naps?

The brain is almost like the Energizer bunny, it keeps going and going and going. The only difference is the "speed" at which it is going.

Since I felt your answer was only half-right, I demurred to Dr. Eric Chudler, Neuroscience researcher at the University of Washington.

According to Dr. Chudler, "The brain is active to different degrees, in different areas, depending on what is being done. Sleep is not a uniform process; rather during sleep, the brain is active in different places in different amounts, depending on what stage of sleep is going on. Similarly, a person watching TV may be paying close attention and being engaged in the program or perhaps not paying any attention to the show at all. These variable will influence how the brain is active and where this activity is taking place."

As for how fast glass cracks, that is another variable answer. It will depend upon the size of the glass and how much force is being exerted upon it.

Although it has not been proven in any lab, you could use a rough formula of F=ma, where F equals force, m equals mass, and a equals acceleration. Given the mass of the glass and the amount of force needed to cause it to crack, you can solve for the acceleration,or speed of the crack.

I'd like to thank Dr. Eric Chudler from the University of Washington for his assitance in answering the first question.
