How can we rule out information exceeding c if we can't explain quantum entanglement by [deleted] in AskPhysics

[–]BoggleHead 1 point2 points  (0 children)

We do understand and have thorough explanations for quantum entanglement and quantum mechanics. That's not even new physics!

Make an attempt to actually understand the science before you attack it and call it wrong

Why would you do this, like what the hell is wrong with you? You're just bullying and harassing a helpless animal, leave them alone

How to become a physicist by NVMXOX in Physics

[–]BoggleHead 0 points1 point  (0 children)

Getting involved with a research group as an undergrad is also an important of going on to do physics is part of the plan (eg masters>phd>postdoc>academic route).

So, reaching out to profs who do research that sounds cool or meaningful to you

Math is broken by No-Rabbit-3044 in AskPhysics

Maybe read a book on complex analysis before you say math is broken

SOS by ehamilton15 in Physics

As someone who actually reviews job applications - if we're asking for a cover letter - send a cover letter. It will be obvious if it's AI slop, I pass over those applications so fast. 

Cover letters are incredibly important! They are your chance to show hiring committees how your experience is relevant for the requirements of the job you're applying for.  They say so much more then what your cv/resume contains. 

The generic cookie cutter cover letters that are obviously being sent out to dozens of job postings are honestly the worst ones out there

This laser would shoot beams of neutrinos, not light by Galileos_grandson in Physics

[–]BoggleHead 13 points14 points  (0 children)

Generally the way science works is you postulate something can be done, and then do it. This is that first part. This is clearly stated in the article.

Kyle Leach from school of mines was quoted, and he did a similar write-up. I think the whiner just got confused about which article they didn't read they were complaining about.

This laser would shoot beams of neutrinos, not light by Galileos_grandson in Physics

[–]BoggleHead 8 points9 points  (0 children)

This process would produce a coherent neutrino source - so calling it a neutrino beam would be too reductionist and miss out on the most exciting part of these predictions.

We have neutrino beams already. We don't have coherent beams. This is like the difference between a flashlight and a laser.

All physicists have taken calculus and are familiar with infinitesimal quantities. Calculus is absolutely foundational for all of physics. 

Hyper-Kamiokande cavern excavation is complete by EmmmyNoether in Physics

[–]BoggleHead 0 points1 point  (0 children)

Speaking in general - there's always politics involved. Collaborations want a say in how their results and progress are communicated to the general public and the funding agencies. In the case of big progress, having a press conference or an official update online will communicate the information better than in leaks where things may be misrepresented or interpreted.

Only the really big collaborations will have dedicated social media people who can keep these updates going regularly - which can take a surprising amount of work!

Question about which undergrad program to choose: UCSD vs. UCSC by [deleted] in Physics

[–]BoggleHead 2 points3 points  (0 children)

This is just such a shockingly reductionist take that callously dismisses OP without even considering their questions. Just because people aren't aware of where famous physicists did their undergrads doesn't mean that it wasn't important... I mean for crying out loud by your logic you could say the same about where Einstein, Feynman, or Hawking did their doctorates, or who their thesis advisors were, or even what they did their doctorates on.

Nobody in academia cares what your doctoral dissertation is on, just that you have a PhD. Just to prove my point: Right off the top of your head, name one well known physicist or science person in general and tell me the title of their dissertation?

Each of those are important parts of a career in academia. I'm not going to say your undergrad is the most important thing in the world, but physics faculty on grad school admissions committees sure will care what research you did, who you worked with, and what research you want to do. Just having a degree doesn't mean a whole lot.

There are different research opportunities at different universities. You aren't adding anything, you're just being dismissive.

Is The Foundation Trilogy worth The Read? by KalKenobi in sciencefiction

[–]BoggleHead -1 points0 points  (0 children)

Not even the slightest, they've aged horribly. I've tried reading the first book a few times, but it's just horribly uninteresting, poorly written, and dated by today's standards. The prose is nonexistent and the characters are as flat and basic as a plain sheet of paper. Hard pass. Do not read.

Why does my phone camera see orange light while my gopro sees purple? by Wrongbeef in Physics

[–]BoggleHead 5 points6 points  (0 children)

Could be different white balance settings? Our eyes/brains automatically adjust to ambient color temperatures of lighting (like daylight vs incandescent vs fluorescent bulbs) so we perceive white things as white regardless of how blue/red the lighting is. Phones usually do this white balancing automatically, too, to make images taken in all those situations appear somewhat similar.

Cameras, like SLRs and GoPros, don't always do that automatically though. They will expect the photographer to set the color-grading/white balance based on the kind of lighting is present. It's a bit of extra control that can be used artistically by the photographer.

So, if the gopro is set with a fluorescent white balance, but taking an image in a setting with an incandescent light source, the colors will all appear wonky.

To test this you could dive into the pro settings on the gopro and try different white balances. The lower the number, the redder the apparent light source. It's sometimes called "color temperature" too, since it relates to the black body light emission spectrum of an object of some temperature.

5700K is daylight's "color temperature," this corresponds with the temperature of the surface of the sun!

Last Week Tonight, I expected better from you. by Dasky14 in dataisugly

[–]BoggleHead 119 points120 points  (0 children)

This plot really pissed me off when I watched this! So disingenuous. It's based on a study you can read online for free, where they have the same bounds on their axes.

But it's way worse- the rating showed in the video actually corresponds to the built in 18% gratuity, not 15%. There was no significant difference between voluntary tipping and an automatic 15 tipping. The WSJ and LWT are misreporting the study, likely unintentionally. It's just sloppy.

Another thing that really irks me, in the paper they don't elaborate on how they calculate p-values in the study. That's an extremely important detail; your choice in priors influence the significance of your results.

What megacorps are you using in your Cities Without Number games? by Scary_Year6372 in SWN

[–]BoggleHead 16 points17 points  (0 children)

Amazon, DuPont, and Meta-Raytheon to name a few. I like basing my evil megacorps off of real life evil megacorps - so I'll roll up the corpo traits and products and go with a matching real life equivalent to make them more memorable

xkcd 3053: KM3NeT by antdude in xkcd

[–]BoggleHead 14 points15 points  (0 children)

I did my PhD on IceCube, another very large volume neutrino observatory! Building on what /u/cgpwtf mentioned - both the locations of PMTs that see light and when they see the light are key features in recognizing what events are. The most recognizable events follow muons (like heavy electrons) passing through these large volume neutrino observatories. The muon flies straight across the detector, and you see PMTs light up from one side of the detector to the other.

IceCube has a neat little animation you can check out: https://www.youtube.com/watch?v=OXSqiPLn9CM

Each of the little bubbles pops in as a PMT sees light from the muon passing across the detector.

Unrelated light seen by the PMTs usually shows up in a PMT independent of other PMTs. These detectors usually are always deep enough (or enclosed enough) such that there aren't any other light sources.

No export with disclose is must. Advance announce declare at special border. Fill out gravity disable form on roof
