Qfwfq Posted February 7, 2008 Report Share Posted February 7, 2008 Is there a similar low grade contempt that exists between mathematicians and pysicists, such as you'll find between architects and engineers?I can imagine the one between architects and engineers, there is a complicated one between mathematicians, theoretical pysicists, experimental pysicists and engineers! :phones: Quote Link to comment Share on other sites More sharing options...
Boerseun Posted February 8, 2008 Author Report Share Posted February 8, 2008 I knew the answer (or an attempt at an answer, I dunno) to this one long, loooong ago, but have since forgotten it. Nevertheless, having been stung by a bee yesterday, this question crossed my mind: What on Earth could be the evolutionary benefit to the little barb-thingy on a bee's stinger that makes it croak after the first sting? I understand that not all victims will pull the barb out, so bees can sting more than once. But once the barb is hooked, the bee dies. So why would it develop the barb in the first place? It seems to me that bees without barbs on their stingers will be much more successful at protecting their hives than those with barbs, and should, theoretically, be selected for? Whazzup wi' this?:hihi: Quote Link to comment Share on other sites More sharing options...

Qfwfq Posted February 8, 2008 Report Share Posted February 8, 2008 So why would it develop the barb in the first place?Once it is hooked, it is a greater problem for the critter that it punctured. If it did evolve that way, then be sure it isn't a great disadvantage. The single worker bee that has the barb is as dispensible as each cell in your body, the organism is the hive. A queen bee doesn't have the barb and they duel each other to the death, one per hive, they don't face the intruder. Quote Link to comment Share on other sites More sharing options...
paigetheoracle Posted February 8, 2008 Report Share Posted February 8, 2008 Why do you sometimes get unfrozen water in glacial ice, if all water freezes at the same temperature? If water is clear, why do bubbles appear white? Quote Link to comment Share on other sites More sharing options...

freeztar Posted February 10, 2008 Report Share Posted February 10, 2008 Why do you sometimes get unfrozen water in glacial ice, if all water freezes at the same temperature? Ummm...does it have to do with melting? If water is clear, why do bubbles appear white? Gas in water, bubbling up, what makes it visible? Is it the result of leprechaun-ish qubits?

Pyrotex Posted February 15, 2008 Report Share Posted February 15, 2008 Why do you sometimes get unfrozen water in glacial ice, if all water freezes at the same temperature? If water is clear, why do bubbles appear white? The temperature at which water freezes is variable -- according to what and how much is disolved in the water. The story goes that Mr. Farenheit calibrated his thermometer by setting 100 as the temp of his armpit (the book didn't say which one) and setting 0 as the temp of a mixture of water, ice and a salt (I forget which one) at solutic and thermal equilibrium. Needless to say, that was 32 degrees F BELOW the freezing point of pure H2O. Therefore, it is entirely likely that impure water would freeze, the solubles getting more and more concentrated into a shrinking bubble, until the remaining liquid had a freeze point way too low for the temperature. Many air bubbles in water are tiny. I mean really tiny. And they act like a microscopic dust and scatter light. This makes the ice go opaque and white. Larger solitary bubbles don't always have a smooth surface on the inside. After the bubble froze, residual water vapor slowly deposited on the inside of the bubble like a frost. Ergo--white bubble.

Boerseun Posted February 16, 2008 Author Report Share Posted February 16, 2008 Why, sometimes, do gas hurt so much? When a bubble of gas takes a corner in your gut and gets stuck somewhere, it hurts like hell. Some people have even been taken up in the Emergency Room, mistaking an internal fart for a heart attack! So, why do you have sensing nerves around your gut? What could the possible use of that be? Or is it simply the gut expanding and putting pressure on an adjacent organ, and what you feel is the other organ being shoved out the way to make way for your inner fart? :) Quote Link to comment Share on other sites More sharing options...

paigetheoracle Posted March 4, 2008 Report Share Posted March 4, 2008 If you're travelling along in a car, with the heating on and wearing a blindfold as a pasenger - how can you tell if you're approaching a snowfield or other cold spot?

Given the above, I think there are much more pressing and immediate questions that wondering about the snow conditions outside. Like "What the hell am I doing blindfolded in a car?", for instance. Other questions coming to mind would be "Where are they taking me?", "Will I ever see my family again?", "These handcuffs are really tight - will they cut circulation to my hands?", "How can I escape?", etc. But when you're kidnapped and blindfolded, pondering local metereological conditions surely counts as stupid, I guess. So, on reflection, I guess the question is allowed. Matter of fact, it fits the bill perfectly... freeztar 1 Quote Link to comment Share on other sites More sharing options...
