I'm so sorry to hear that, exchemist. I don't know what to say.
Anyway, thanks fellow sciforums members for the feedback. My sudden appearance here was not due to chance. It was prompted by reading a comment...
Ninja'd by billvon, too!
Es exchemist points out, HIV infection should be amenable to a vaccination treatment. In AIDS, the damage done to the immune system does not occur...
To be fair, my friend wasn't accusatory in his bitterness. It was more his lamenting (thanks for reminding me of that word) the loss of former...
I'll pass that kind thought on to him.
These days he runs retreats counselling youngsters how to cope, how to come out to family, how to find space. The camp site facilities are impressive...
Well, I was surprised to hear it from him for the first time last year. But then, for me AIDS was something that wasn't my problem. Money and...
I could make the same point about diseases rife in Africa such as malaria.
It doesn't alter the fact that he is bitter. He lost a lot of friends who may have survived if it was realised sooner that it was a virus and not a...
A gay friend of mine is still bitter at the contrast between the enormous effort put into developing vaccines against Covid and that into developing...
In Classical Greek δός μοι πού στω και κινήσω την γην Apologies for "incorrect" post. Classical=>Attic=>Doric But the sentiment is the same. With...
δος μοι που στω και κινω την γην In fact, much work was done with models in still air using exercise treadmills.
What Dave said. Think about it. If the wind were not blowing, in still air (relative to ground surface) the cart will not move. The energy in moving...
Sure. But no wind-powered vehicle on land, water or ice with any arrangement of sails can exceed windspeed going directly downwind. Agreed?
Ah we have a skeptic. Have you glanced at any previous comments?
Are you sure about the precise constraints I'm setting? Wind heading Let me be clear as I can. The wind is blowing consistently from East to West at...
No question sailboats can exceed wind speed. Ice yachts more so. What neither can do is sail directly downwind at greater than windspeed.
There has to be a transfer of kinetic energy. Air molecules are slowed by loss of momentum which is gained by the sail.
@ Rainbow. Wind, in this instance can be construed as air in movement with respect to another medium.
