He noticed that chemical reactions always happened in small whole number ratios of mass. From that he hypothesised the existence of atoms. But Brownian motion is arguably the first direct evidence.

Well done, but he actually published 5 papers in 1905, his annus mirabilis. These were 1) On the Electrodynamics of Moving. Bodies (Special Relativity) 2) Does the Inertia of a Body Depend on its Energy Content (a study of the consequences of the first reference, where he derived the equivalence of mass and energy i..e. e = mc^2. 3) On the Heuristic Point of View Concerning the Production and Transformation of Light (the photoelectric effect, that ushered in the quantum revolution and his 1921 Nobel Prize) 4) A New Determination of Molecular Dimensions, used to calculate Avogadro's Number and the size of molecules. This paper was in fact a summary of his doctoral dissertation. 5) On the Motion of Small Particles Suspended in Liquids at Rest Required by the Molecular-Kinetic Theory of Heat, which explained Brownian motion as the result of molecular collisions. This insight did in fact lead to a second Nobel Prize in 1926 to Jean Perrin. The five papers are collected together with annotations by John Stachel and a foreword by Roger Penrose, called "Einstein's Miraculous Year"

If you are interested in looking inside of quartz or other crystals, there are many very simple, cheap ways of doing it. We do it in the lab, and there are plenty of papers that actually look at the water within crystals as they tell us a great about about the time at formation of the crystals. We do it for glass inclusions as well. Reach out to a research geologist, and I'm sure someone would be happy to help with your demonstrations, including myself.

The random motion of atoms and free electrons in a conductor, which causes Briwnian motion in fluids, also causes random “thermal” noise in a conductor, with a voltage amplitude proportional to the resistance of the conductor and its Kelvin temperature. This is used to “squelch” radio receivers when no one is transmitting on a channel.

@neutra__l8525

Ай бұрын

Is the term Brownian motion used for fluids only, or does the term apply when dealing with solids also. When you say you can squelch it, is that because you are increasing the noise so that the signal is lost? Why do you want to squelch a radio receiver that no one is transmitting on.. wouldnt you squelch one that is being transmitted on?.. and is this how radio signals are jammed, by causing an increase in thermal noise at the receiver/transmitter? Lastly, PC's sometimes have a temp sensitive part that is used to generate a random number by (I think) letting the voltage of the noise represent a 0 or a 1 in binary. Is this how that type of RNG operates?

@@neutra__l8525 In a solid that conducts electric current, some of the electrons are free to move among the atoms, and thus behave like a fluid. The term “squelch” refers to silencing the random noise resulting from the random motion of electrons that comes from the speaker between transmissions, which is very annoying, especially in sensitive FM communications receivers. Basically, a receiver sensitive enough to hear the stations you wish to talk to will, between calls, produce a very loud “white” noise if the audio is left on at a normal volume. When a coherent signal comes in, the math of how FM detectors work overwhelms or “quiets” the noise. Since the noise has frequency components above the range of signals that are deliberately transmitted, part of the detector output is tapped off, amplified in the “noise amplifier” (that is its actual name), and rectified to produce a DC bias voltage proportional to the amount of noise detected. When that DC voltage reaches a certain level (which can usually be adjusted with a knob), the audio amplifier is cut off, or “squelched.” When a call comes in on a channel, the noise drops below the threshold, and the audio comes on. When the transmission stops, after a fraction of a second called the “squelch tail,” which sounds like a short burst of white noise, the audio cuts off again. Many applications, such as police and fire radios, aircraft radios (they are usually AM, but a similar system works with AM also), or even two or more “ham” operators talking, require a frequency to be monitored for occasional calls, and the squelch makes monitoring much less stressful, and allows the use of audio for other purposes while waiting.

In high school chem lab we measured Avogadro's number by spreading a known (mass) drop of oleic acid over a tray of water and measuring the area of the monomomolecular layer "lake" formed since one end is hydrophylic.and the other is hydrophobic. From this we could extimate the volume of a molecule. Dividing the volume of a molecule by the volume of a mole of them, we could get Avogadro's #.

Thanks for this video and you allowed me to clarify further reasons why I no longer just accept the atomic theory. The two pieces of glass used in setting up a slide for a microscope allows for one more reason for me to be skeptical of the theory. One has to assume this unseen atom to begin with and not leave it as an unknown to seek to learn about. The other part is the glass over liquid has to be viewed as a non factor when it is an actual part of the setup to see the phenomenon in question. This effect can have other factors that would necessitate further falsification experimentation to narrow down possible cause instead of accepting an unseen cause.

2:53 a key difference in the movement is that the dashing movements that the biological reference side did were not in the red non biological sample the video discussed Because the right side is moving how it is while the left is not it makes me wonder if the movement on the right is the movement of the parts that make it, a shake from vibrations, or a visually localized reaction to magnetic fields or poles
