The more I think about it, the more it seems to me that astrology is not complete nonsense, and in times before such fast transportation and import could perhaps have even been quite accurate. What say you, /lab/?

I am only talking about personailities being predicted by the time of year they were born in, nominally defined by the stars that happen to be above at the time. It is entirely scientific.

The GOCE geoid map has been released. You can clearly see major subduction zones and I suspect it is also displaying things such as north atlantic deepwater production zones and such like.

Not >>1445, but I don't see what's so TROLOLOLO about this. I don't know what GOCE is, hence the map doesn't make very much sense to me like this. Latitude/longitude in degrees is pretty much the only sensible interpretation for the labeling of the axes, but I have no idea what the colouring means. A unit might help. And it's certainly not elevation in metres.

Alright. Just putting that below the colour key would have helped tremendously, and if you just had the diagram like it is and not the information that it is from GOCE, I consider it undebatable that the diagram would be useless.

It reached my ear, from two different, possibly independent sources, that an experiment at the Tevatron is about to release some evidence of a light Higgs boson signal. Some say a three-sigma effect, others do not make explicit claims but talk of a unexpected result. That the result comes from the Tevatron is for sure, since the LHC experiments do not have nearly enough data yet to search for that elusive particle, and other particle physics experiments in the world have not nearly enough energy to produce it. However, I am unable to understand whether the rumor comes from CDF or from D0.

http://www.science20.com/quantum_diaries_survivor/rumors_about_light_higgs

Has the Tevatron beaten the LHC to it?

1479 Allergy to Barley = Allergy to Beer/Whiskey?
Looking for a biochemist/whiskeyfag here.

Someone posed an interesting question to me earlier, over whether a person who was allergic to barley would be allergic to beer or whiskey. Now, I simply don't know enough about the chemical side of the malting, fermenting and distillation processes involved in making these two beverages (yes I know beer isn't distilled), and the overall composition of the beverages you get at the end of the process to answer this myself. Is there enough of the barley left at the end to cause the same allergic reaction in the patient? This is purely a little bit of pondering on my part, as one of the resident medfags I understand immune response pretty well - I just don't know enough about brewing or whiskey making to know if they can still contain the same allergens at the end of the process.

TL;DR - What's actually IN beer/whiskey at the chemical level?

As someone who's (instantly and obviously) allergic to wheat, barley, corn, and many other cereals when eaten* I can confirm that whatever there is in beer, even weissbiers, doesn't cause me any more hassles than the next man. Whisky likewise.
Damned if I know what the missing part is, but I'm happy that it's not present. Not least because there's a beer festival starting tomorrow, and it's within walking distance.
Sorry, no science, just anecdotal from a self-experimenting guinea pig, to whom this stuff matters.

That wasn't meat to be an /emo/ whine, despite sounding like it. Much more an offer to try random shit, to see what happens, and an expression of interest in finding the same answers you're looking for.
Another datapoint - alcohol-free beer is also fine, so it's not that the alcohol counteracts / makes ignorable the effects.

1338 What is time?
Hello scientists.

Yesterday I watched a documentary that really fucked with my head. I have always thought of myself as someone interested in science but Ive never asked myself the fundamental question of what is time.

Its been bothering me all day

Inb4 Arrow of time- measure of entropy, measure of length of duration, a perception and all the other non answers.

How can one explain time, without relying on using the very concept of time one is trying to describe. Is it even a "concept" or is it something more fundamental than that?

In principle you're right, but they actually did send two airplanes (one westward and one eastward). and you also have to take General Relativity into account to explain the results.

An additional question. (A warning, this is probably very infantile

So, taking into account time as a constant present idea, does this mean that the pre big band universe was simply a timeless universe? Not as in nothing happened, but everything happened at once (as in the whole universe, beginning to end), time being almost a theoretital 'brake'? I mean taking into account the behavior of light as a constant even in different frames of reference, doesnt this point to the possibility of timelessness?

1454 Fans.
Hi lads. It me again. It's about time we had another crazy idea.

Here's my recurring thought. Supposing you have a fan, which is switched on, visible the blades turn transparent and you can see through it.

Since matter has a huge electromagnetic component, just like light does, is it theoretically possible for a fan to spin soo fast than matter can pass straight through it without smashing the blades, or getting broken itself ?

If not will the fan blades become so "solid" that it will completely block light from getting through, like full 360 degree polarisation?
