Behold the bacteriaphage. This virus is known to hunt down bacteria such as e.coli and implants its DNA into such bacteria so that e.coli will replicate with the phages DNA. Eventually the e.coli cell will explode into more of these phages.

Also without biology you elitist physicists would have died from sickness long ago.

that looks loving sweet, but it will make you sick... :C

In highschool I learned that the Russians did a study on them and used them as a cheap treatment for sickness. It is currently believed that they might be the answer to drug resistant bacteria such as MRSA.

Just gonna throw this random fact out here:
A star's life is a constant battle between strong gravitational force trying to collapse the star due to its mass, and the outstanding pressure created by nuclear fusion (1 hydrogen atom + 1 hydrogen atom= 1 helium atom), which pushes towards the star's surface, counteracting the inward pressure of gravity.

My grade is a 91 forgetin' A rite brother

I had a 102 for the quarter and got a 96 for the semester. Anyways, yes I do love physics.

[Harm94]

I'd say chemistry and physicists are pretty popular subjects in the fields of science.

Has physics explained why boiling water freezes faster than cold water?

I do believe there is no proven reason yet, but my best guess is that either some of it evaporates meaning less water to freeze, or perhaps little air bubbles in the liquid act as 'seeds' for the ice crystals to start forming

I always thought that hot water molecules are more willing to loose energy

Yes, but I am almost certain that temperature does not have a momentum.

Currently learning about the electromagnetic spectrum in physics

fun stuff like that

Temperature is a measure of kinetic energy. All of the particles being measured certainly have momentum.

Also I made this for fun so you guys should watch it!!!

Why would you be mad? Evolution is like one of the least important topics to cover thoroughly in biology because it is really basic. You read the chapter once, take the test, and then you know everything important about it. It says that 28 percent of science teachers craft lesson plans with evolution as the main theme. That is too much. If you have to spend that much effort on teaching evolution, then the kids you teach must be idiots.

I'm mad because people deny it even happened.

Is it me, or do most of the southern states hve higher grades then those north states up there?

Yes the atoms 'jiggle' and as they loose energy to their surroundings they jiggle less. The particles have momentum, but the rate of which this energy is lost does not.
