for their relative brain sizes‚ which scale in proportion to body size. Human one’s weight 1.5 kilograms‚ elephant brains 5 kilograms‚ and whale brains 9 kilograms. Yet on a per weight basis‚ humans pack in more neurons than any other species. This dense packing is what makes us so smart. There is a trade-off between body size and the number of neurons a primate including us‚ can sustain. A 25-kilogram ape has to eat 8 hours a day to uphold a brain with 53 billion neurons.

Practical Magic: The Therapeutic Effects of Psilocybin on Affect Regulation An interesting new development is taking place in pharmacological research. Neuroscientists are picking up where they left off in 1971 and continuing their research on the psychotropic effects of psilocybin‚ many of which have therapeutic value. There are many ways in which psilocybin works‚ yet its main mechanism of action seems to be reducing activity in the amygdala via its effects on the serotonergic system. It is through

Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive.[1] Even small nuclear devices can devastate a city. Nuclear weapons are considered weapons of mass destruction‚ and their use and control has been a major aspect of international

time. All moving objects have a quantity of motion‚ otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms and velocity is measured in meters per second‚ the unit for momentum is kilogram meters per second. Similar to velocity‚ acceleration‚ and force‚ momentum is also described by its direction along with its quantity. The momentum of an object will always be in the same direction of its velocity
