A wonderful lecture. Thank you so much for the information and profound presentation. Maybe that Neutrino Ghosts will show us ways to reveal a lot of hidden secrets of the Universe.

This is a phenomenal lecture. I think she did a great job with the pulmonary information for those who are not already familiar with basic material. But his description of the various problems in data acquisition will absolutely amazing. Infosys circuit designer and a computer programmer and architect and these considerations that he was describing are quite amazing. I suddenly realize why LHC detectors Atlas and the other one are so huge. Among other things outside of the various devices that detect electrons and protons and photons and someone does all the number of wires that need to be managed millions of wires and getting them all from one place to the other with minimal moist and insufficiently short distances is such a difficult problem. I remember designing and kissed system for a supercomputer and problem I had was that speed of light was too slow given the length of the cables. I I had to put an absolute limit on the length on a cable so that there is a guarantee that the signal on it could be locked. And I don't think I ever appreciated the difficulty of this before. He's got me thinking about these problems in a very different way than I ever have. I can only say Bravo for a wonderfully stimulating lecture

Hi i'm not a scientist or knowledgeable on any of these things, but in supposition that all known forces in the universe were once unified, wouldn't the energy level required for that be much lower then we expect it to be, this idea came to me because of the weak influence gravity has compared to other such energy fields like electro-magnetism etc. curious what your thoughts are on this.

I am thinking out loud, you can compress raw data on fly with XOR functions on plc (fpga) and then create images on a large computer and compress it with lossless compression, its better to make your own optimized silicon chips instead for this purpose than using off the shelf fpga that are not perfectly optimized for application but money, yeah. I love these kinds of problems, like geometry based noise reduction, etc.

There is a danger of throwing out everything other than 'expected' events, in there is some data at a more physical level that could lead to an unexpected discovery.

How do one makes neutrino beam? How you direct neutrino beam to the detector?
@GuilhermeLima-bq6bb

Great question! Beams of pions (and some rare kaons) are quite easy to produce, and also to point in the desired direction. Pions then decay producing neutrinos, which by momentum conservation, will have *mostly* the same direction as the original pions, this is the neutrino beam. Not as well collimated as the original pion beam, but still quite well collimated to have many of them hitting the detectors hundreds of miles away.
@Thomas..Anderson

Hmmm. Why do ionization electrons travel at constant speed? They should start with some speed (i.e. kinetic energy) and from then on they should accelerate in the direction towards wires, due to electric field between cathode and wires. Or is there some effect at play slowing them down at exactly the same rate as electric field would accelerate them. Like collision with those orgone atoms (wink)?

What is the speed of neutrinos? If they have mass then it can't be at the speed of light.
@GuilhermeLima-bq6bb
3 жыл бұрын
Great question! You are totally right, in that only massless particles can travel at the speed of light. In fact neutrinos are the lightest particles there are so far, therefore they always travel very very veeery close to speed of light, to the point of being experimentally quite difficult to measure that difference in speeds.

Weak interaction Question... During Beta decay the decay energy is shared by the Beta particle and the Neutrino. The measured Beta particle has an energy that differs for every individual Beta decay. The rest of the energy is taken away by the Neutrino. The sum must be equal to the endpoint energy. But what process decides in each case how much energy the individual Beta respective Neutrino will have?

@*Floofy shibe* Yes, in the sense that particle physicists have in mind their physics goals, rather than developing new circuitry -- although it is not uncommon that they need to develop new circuitry in order to reach faster data acquisition or triggering performance, for instance. It is just not their primary goal.

2:07 I guess I am an elitist of sorts. Specifically, his use of an image from a Wiki site. I don't believe any site that has the word "Wiki" should be used a a credible source in any academic paper or presentation. The caffeine is correct, but as a scientist he could have captured an image from pubchem.ncbi.nlm.nih.gov/compound/caffeine. 3:02 I wish people would stop saying electrons "orbit" the nucleus and stop depicting atoms as little solar systems with electrons orbiting like planets. Those complaints, however, are minor and the lecture as a whole was very informative.
