The particles could be too small, or moving too fast, to be seen, or perhaps our eyes see right through them. As it turns out, all of these theories are both right and wrong at once. And they're all useful in describing certain behaviors of light....
Inside the control unit (on the right hand side in the above image) is a small DC motor which drives this gear: You can see that, attached to the gear, there is a small weight. This weight is about the size of a stack of 5 U.S. nickels, and it is mounted off-center on the ...
volume becomes smaller than the resolution of the instrument (c). Larger pores are visible in the more viscous cement, Poly (b). With ageing, an overall reduction in the pore size was also observed for the latter, although no significant changes in the small pore range can be noticed (d...

The pressure is high enough to force atoms of hydrogen to come together innuclear fusionreactions — something we try to emulate here on Earth. Two atoms of hydrogen are combined to create helium-4 and energy in several steps: Two protons combine to form a deuteriumatom(hydrogen atom with on...
seems to be something amiss about “ordinary” matter as well. When observations are matched up with the leading theory about cosmic composition,physicists can’t account for 30 to 40 percent of the universe’s baryonic matter, which comes in the form of such particles as protons and neutrons...
and a fairly consistent benchmark of launching the Kerbal X straight up and stopping the benchmark as I reached 70km. Also tested three different protons, all had the same performance. According to another report, EVE WILL BE BUGGY/NOT WORK on the NATIVE version, so, it's good that the...
Indeed, our quarks, which are basic particles, stay neatly packaged inside the protons and neutrons. But in strange matter, there are no boundaries; it's just a lump in which the quarks run amok, roaming top to bottom and end to end. Did we mention that strange matter isn't known to...
Exactly, how small are atoms? Include an analogy. Compare magnetic and electrostatic forces. In what ways are they similar and different? What is the difference between bulk and nano particles? If two radioactive samples have the same activity measured in curies, will they necessarily create the...
If you boost a gas toextremely high temperatures, you get plasma. The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus (seeHow Atoms Work), surrounded by a cloud of electrons. ...
