However, there is mounting scientific evidence to suggest that yawning has more to do with temperature than oxygen. As brain temperature rises, concentration and memory suffer, and a number of tests in humans and animals have shown that yawning is linked to heat,… Read more →
For most (if not all) people, their voice sounds a lot deeper when they’ve just woken, compared to how they sound during the day. This effect can easily last for a few hours, like for me today.

The differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. This function provides proportional RPMs between the left and right wheels. If the inside tire rotates 15 RPM less in a… Read more →
A Musical Fountain, also known as a dancing fountain, is a type of animated fountain for entertainment purposes that creates an aesthetic design (including three-dimensional images). This is achieved by employing the effects of timed sound waves and timed light (including laser) against water particles. Modern-day fountains employ a computer-controlled pneumatic arrangement, essentially a pressurized cylinder of water with the… Read more →
