Why do people have to leave each other? I dreamt that I was sitting inside a masjid and a little girl walked up to ask me a question. I was one to get attached.
Some planes in the sky leave trails that persist and spread, and other planes, in the same sky, leave short-lived trails, or no trails at all. Contrails are actually a type of cirrus cloud. When the air is wet and cold enough the trails can stay around for a long time, and sometimes spread out.
So you see helpful images like this.
But this is wrong. Contrails can fade away, and contrails can persist and spread. It depends on the air they are formed in. Now there are two main reasons why some planes leave trails and some nearby planes do not.
The less common reason, is that different planes have different engines. Some engines will leave a contrail in air where another engine will not. Here, for example are an Airbus A maiden flight: You can also get a similar effect with engines at different power settings, especially if it affects the exhaust temperature.
This can occasionally be seen with high altitude refueling, when the plane being refueled cuts the throttle to near idle in order to separate from the tanker. The planes are at different altitudes. The reason that one plane makes contrails, or makes contrails that persist, and the other plane does not, is that they are in different regions of air.
When the plane is in wet air, it makes a contrail. In dry air it does not.
Surely, you might object, they would have to be miles apart? Well, no, and that brings me to another point I fear I must emphasise: Wet and dry air can exist within a few feet of each other.
Consider, for example, clouds: Look at the bottom of those clouds, see them extend off into the distance. They form a layer at a specific altitude.
Above that altitude there are clouds. Below it there are no clouds. The difference between clouds and no clouds is just a few feet. Now those are low altitude cumulus couds. Again they are in a flat layer.FREE COURSE THE WORLD, THE JEWS AND THE SCIENCE OF HUMAN SURVIVAL Anti-Semitism, division, separation, violent conflicts and a general breakdown of the institutions of human society.

As soon as the Confederates laid down their arms, some. Organizations are often run according to "the superchicken model," where the value is placed on star employees who outperform others.
And yet, this isn't what drives the most high-achieving teams. Business leader Margaret Heffernan observes that it is social cohesion — built every coffee break, every time one team member asks another for help — that leads over time to great results.
Jul 27, · The new math of the ‘60s, the new new math of the ‘80s and today’s Common Core math all stem from the idea that the traditional way of teaching math simply does not work.
As a nation, we. Do we really forget? Many people think that the human mind is too complex to explain, and memory is no exception. Even though vast amounts of research have been carried out into how we remember (and forget!) things, nobody knows for sure the model on which human memory is based.
