Wow.Rock walls.Looks like a collapsed dolmen maybe...yeah...everyone I'm getting ahold of on RU-vid has a piece of the puzzle.you're not going to believe how big it is.
There are too many, disparate types of imagined reasons for the aggragations.. I live in a huge forest, wit 2000 people in nort-centralMassa-choose-its. One a mi friens, bout a big piece of land to protect the standing stones, made her case, about history, and , what.
We study these, they are definitely not the result of clearing farm fields. That fallacy has been proven wrong over and over again several years ago. These are effigies, ceremonial sites. Look up Stephen Carney, Stonewall research II, and the other people who actively study these today. People who learn Stone art often times to teach others how to see it, like myself. Paleo Mountain Man (RIP) has them on his property too.
You need to catch up and not keep on misinforming people of these old ideas. This is all been proven over and over again several years ago and it’s now common knowledge that these are not from the farm fields. It’s OK if you didn’t know, but just try NOT* to spread out misinformation. ❤
@@FacesintheStoneI’m a stone mason. They’re from clearing fields. If they were ‘ceremonial’ they would have done a better job instead of just plunking them down however. And yes, I know time has gone by. My walls will last centuries nearly intact.
you got the idea with the souck blousing but if you were to use some tape around your ankles you would trap them from crawling up further :) , we used to used flea collars around our boots when they are real thick , chiggers are the worst tho
A Native American stone mortar and Manitou stone. This recording was made on the summer solstice at a site near the stone wall shown in my recent post. I feel so blessed by the history found in the landscape that the ancestors of the Native People in RI left for me to discover today. They suffered so much so long ago. Happy Indigenous People Day.
The launch angle is about 4 degrees but this is not critical. It can be launched at a higher or lower angle and still work correctly. Because the launch angle only influences the frequency of the oscillation and has no effect on the direction of the plane of oscillation. The direction of the plane of oscillation only changes because of the Coriolis Force, which is constant no matter the launch angle.
@@jazzani95 Muchas gracias Jerry por tus orientaciones,otra pregunta sabes como puedo ponerle un dispositivo electronico para que no se pare,y dure por lo menos 24 horas para ver el efecto de foucault mejor?,ya que en la zona de mi pais Republica dominicana,la rotacion es baja para 1hora
@@fundamentosdeingenieriamec8509 It is not trivial to drive a Foucault pendulum so that it will sustain the amplitude of oscillation. Because the driving force must be designed so that it does not interfere with the direction of the plane of oscillation. The only advice I can offer is to refer you to this article published in the American Journal of Physics and to give you a link to a driven Foucault pendulum that was constructed from this design.: R.

Nice. Based on my own attempt to build a pendulum the pendulum in this video is exceptionally good at resisting elliptical precession (undesirable) for such a short cable. You mentioned in one of your other comments that you used a "wall flange", so maybe that's an important part. Did it precess at the expected rate for your latitude?
Hi Steven, yes the rate of precession is correct for our latitude. More info here, docs.google.com/document/d/1r27VunSb9hXDuLPw798PxEp8laVfKY3pd8jh--bOhrc/edit
If you are Gerald Zani from Brown University, I could really use some advice on a Van Der Graff. If you would be willing to help, I will give you my email so we can talk about it. Thanks in advance.
When liquid helium has passed through the lambda point transition and has become a superfluid then it can pass through a superleak. A superleak is a leak that is so small it is microscopic and an ordinary liquid that has viscosity cannot pass through it. But superfluid helium has no viscosity and therefore can pass through a microscopic superleak.
@@GeraldZani Would it be hypothetically possible to make a "perfect container", that is flawless with no superleak? or is it just the space between the atoms that make the leaks possible? Even if we could, the superfluid helium would still "climb" on the wall of the container and leak right?

Thanks for the information. Do you know if such an experiment exists? All the text books say that when particle detectors are placed in each slit, only two band appear. The argument is based on the assumption that when a particle is observed, it materializes and hence, we can trace back the origin of that particle.
I recommend to watch the Richard Feynman Messenger Lectures, Lecture number 6, The Quantum Mechanical View of Nature. www.cornell.edu/video/richard-feynman-messenger-lecture-6-probability-uncertainty-quantum-mechanical-view-nature
The lecture is indeed fantastic. But, again, we don't have access to the raw data. The authority of Feynman, however, more than compensates this apparent absence of information:)

This is not easy to make correctly. Get a wall flange, a rod, a pin vise and monofilament fishing line for the string. Mount the wall flange to a brick wall to act as a very rigid support to hold the rod and pin vise up. Thread the string down through the pin vise. If the support is not strong then an elliptical motion will occur instead of a straight line motion. Use a massive the pendulum bob. Start the pendulum carefully so it does not bounce. For more details read wiki.brown.edu/confluence/display/PhysicsLabs/1E20.10+Classroom+Foucault+Pendulum and also read the article published in The Physics Teacher magazine, 34th edition, pp. 238-239 (1996), “Apparatus for Teaching Physics: Classroom Foucault Pendulum”, by John E. Horne. This magazine is published by the AAPT. If you have trouble then contact me again. Good Luck!
Well you kind of answered yourself. If space is a vacuum that means there is no helium in space. In reality you can find atoms here an there, but the only place where there are large enough quantities of helium to even go through this process are stars and gas giants. There is definitely liquid helium inside the gas giants in our solar system.
In this experiment the temperature of the liquid Helium is controlled by the pressure. The pressure on the Helium is pumped until a temperature of -454.8 F (2.7 Kelvin) is achieved, which is the temperature for the lambda point transition at which the normal fluid helium I makes the transition to become the superfluid helium II. If you watch and listen to the video carefully at 11:45 the boiling in the liquid helium suddenly stops when the lambda point transition occurs. The bubbles appear because the video camera is looking through an outer dewar of outer liquid nitrogen. Let me know if you have more questions. wiki.brown.edu/confluence/display/PhysicsLabs/7A70.50+Superfluid+Helium
you won't find much of anything beyond these standard experiments. i am curious of things as well. like what if you put a block in the fluid, and put an equal block of mass, with a flat surface on flat surface, then as the layer of helium covers the one block. will the top block move? or does the 0 viscosity just coat both blocks?
