Objectively speaking (but, of course, I'm interested in other points of view) research into "pure science" starts out as innocent intellectual curiosity and ends up killing people. What have we gained from nuclear physics, so far, besides atomic bombs and nuclear reactors? These huge public science projects are work-fare for scientists so that they'll be available to build the next big weapon (if they don't blow us up by accident along the way).

First off you're rather quick to discount nuclear power... that's a huge step in clean energy. But ok, you want to discount that I'm game. What has nuclear physics done for us... it grew the ability for medical imaging by leaps and bounds allowing us to have a much more effecient diagnosis procedure in our medicine. The knowledge regarding half life allowed us to date ancient artifacts much more precicely which hugely helped archeologists. It led to the development of proton therapy for cancer which has saved my grandfathers life. and that clean energy thing, but we won't mention that.

So yeah as you said science doesn't do anything for us.

OK, I stand corrected ... and I'm happy for your grandfather, but what's clean about nuclear energy? It's dangerous (Chernobyl) and leaves a lot of waste that we still don't know what to do with.

The CERN is only a few miles away from my place, and - besides tentacles - I look almost like you

People from the CERN made this video - I don't like rap but this is cool - because there is some sort of "controversy": a few people and scientists are saying that the CERN will create a black hole and that the earth will be destroyed... I haven't made that much physics but that sounds a little far too stretch.The CERN has been created in 1954 and didn't had one major incident - I can't even remember of a small one (that doesn't mean there could not be one, but the people working there are the cream of the professional...) btw the WWW was invented there by Tim Berners-Lee and Robert Cailliau...

When the train was invented, they were people and scientists saying that this was impossible because our body would never survive such a speed (If I remember well they wanted to go as fast as 30km/h) or that we will die suffocating because the speed of the air would not let us breathe... hopefully, we didn't stop at those considerations...

I will not enter the usual debate about what fundamental physics can bring us that is good... I think that if you have entered an hospital today the answer will be obvious. But if you are interested in reading more about the CERN and the use of basic science, there is a nice paper there: CERN - The use of basic science

True the waste is a problem, but at least it's containable. as for chernobyl yeah that was bad, but it was also built shoddily and barely maintained. compare the number of plants in extince to the number of disasters caused by them.

I live in an area surrounded by nuclear plants and have never had a problem.

PS: Sorry for the previous post btw, got a bit heated by the argument that science in general isn't good. I was prepared for arguments against the LHC but not science in general.

There are actually a lot of smaller colilders in existence, one not horribly far from me in central california. most scientists say a black hole probably won't form, but even if it does I won't care the next day

I am a big fan of science for curiosity... or better: research for curiosity (I like to enlarge the vision to humanities for instance)... So I think that wanting to answer the questions a human mind can have (what make us what we really are is the fact that we can think and even ask question about our own thinking) is one of the better way to honor what we are - of course, when harm could be done, experimentation must be done with caution and ethic-.

I just wanted to add this to lighten my point:
The point (application of particle studies) was elegantly, if arrogantly, made by Bob Wilson (first Director of Fermilab, a large particle physics/accelerator laboratory near Chicago) who, when asked by a Congressional Committee "What will your lab contribute to the defence of the US?", replied "Nothing, but it will make it worth defending"

That's OK, my clothes were a little singed but no flesh. I'm not trying to say that nothing good comes from basic science but that it's a question of proportion. For example, on the negative side nuclear physics gave us the atom bomb (Hiroshima and Nagasaki), the cold war, tens of thousands of nuclear war heads and depleted uranium. If it were possible to draft a balance sheet of benefit versus harm, I think we'd be surprised by how negative it is. Your grandfather and the archeological artificats on the plus side and the War in Iraq (weapons of mass destruction), 200 Israeli nukes and Iran enriching uranium on the other... See where I'm coming from? I'm not saying that we shouldn't do science because no one's going to stop it, anyway. I'm just saying that I used to feel that "progress" was a good thing and now I'm beginning to see the dark side.

I lived near Fermilab for twenty years and I can honestly say that it didn't do me any harm except that, every now and then, I get this pain in my back...
