An experiment in Germany has made the most precise measurement yet of the maximum mass of neutrinos β€” light subatomic particles thatare so devilishly difficult to measure that physicists have only been able to estimate the upper limit of their mass. They weigh at most 1.1 electronvolts. nature.com/articles/d4158…

Binary systems with Wolf-Rayet stars and massive OB companions generate strong stellar winds. New data suggests that when these stellar pairs orbit in close proximity to each other, their stellar wind collisions can generate photonic energies in excess of 100 mega electronvolts, MeV. upi.com/Science_News/2016…

What exactly is an electronvolt?

I've been reading some of the material regarding the LHCs startup lately, and how it's going to be running 13TeV experiments. My question is, what exactly is an electronvolt? How can I put it in context (in terms of volts, joules, whatever it's equivalent to). Also, I've heard it being used as a unit of weight for subatomic particles, is this true, and how is it possible?

Why are particle masses measured in electronvolts?

For example, I recall the Higgs Boson being predicted to have a rest mass around 120-5 GeV. Why do particle physicists measure these masses in terms of eV and not joules or kg? Is it because of convenient numbers?

As an aside, I've also noticed that c is often set to one in these kind of energy/mass calculations. Is this also because of 'cleaner' mathematics? How does this affect the standard relativistic equations used in particle physics?

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Just because it's a joke, doesn't mean it's a dad joke

Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.

THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB

Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"

I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual

So check out r/jokes for all types of jokes

r/unclejokes for dirty jokes

r/3amjokes for real weird and alot of OC

r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes

Punchline !

Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub

Edit 2: don't touch the thermostat

Petition to ban rants from this sub

Ants don’t even have the concept fathers, let alone a good dad joke. Keep r/ants out of my r/dadjokes.

But no, seriously. I understand rule 7 is great to have intelligent discussion, but sometimes it feels like 1 in 10 posts here is someone getting upset about the jokes on this sub. Let the mods deal with it, they regulate the sub.
