In a more scifi military sense, if a space battleship wants to use its laser cannons to strafe ground targets, the laser has to use frequencies longer than the vacuum frequencies or they will be cut off by the atmosphere.
IR is great for a weapon, since heating is hurting. But far infrared gets blocked by moisture in the air.
@kilroy_was_here I usually just assume its the french's fault fromt he get go anyway
You ever wonder why the small band of spectrum we can see (called visible light) is special? I mean almost all animals see in light ranges are are somewhere around here. I mean sure some can see a little farther into IR or UV but in general all animals see roughly around this same narrow band of frequencies in an otherwise infinite spectrum... So what is so special?
Its actually a quantum thing. Everything roughly around visible light and higher interacts with material by electrons jumping energy levels. However IR energy is absorbed by the bonds between molecules instead, which is why IR represents heat.
Basically visible light is right where these two modes intersect. Essentially they are the lowest energy part of the spectrum that is still high enough energy to interact primarily through changing energy levels of electrons. Essentially any more energy and it wont really get through the atmosphere as extreme UV is cut off.. any lower and it wouldnt be very effecieient cause most of the energy goes to heating the eye rather than seeing... So its right in that sweet spot.
@murshedz Can you please link the study so we can fact check and learn, thanks.

The law quoted in the article:
"It should be pronounced in three (3) syllables, with the final "s" silent, the "a" in each syllable with the Italian sound, and the accent on the first and last syllables"
Italian sound? Sounds to me like it should be A-kan-sAH, -saw doesn't sound very Italian...
Yes it was a district of Syria at first in 500 BCE it was..
Yes there were times where the region was independent and not ruled by another. But im not sure you can call it a kingdom because im pretty sure they were nomadic and didnt have much need for a more formal government during those periods.
But yea palestine was a region that for much of its history was indeed part of other larger regions/countries.
I was thinking about that.. and im not sure thats entierly accurate.. i mean higher frequencies, sure the super high stuff is obviously very penetrating... but the low stuff seems to be a mixed bag depending on how low and what material.. For example a lot of IR thats at a medium level doesnt penetrate trough too much... but extremely low IR like near 0 hz is going to be very penetrating through a lot of stuff.. but then you also get some weird effects too.
Thanks, I understand your frustration with mandates, I do... but yea its important we try to not let all the ugliness turn us against eachother.. that doesnt do any good for anyone.
I appreciate and respect you recognize that, its why I think so highly of you, your a good person, we all slip up, no worries. Thanks!
The point here is its very individual to the plant but its usually some combination of daylight hours and temperature.
It is very cool though how if you want to raise plant you have to know specifical what signals it so youc an control that.
Assuming that is your question then the earliest known map was in 150 AD, Ptolemy's map of Palestine. It labels the land as "palestini" in greek, essentially Palestine.
There are of course countless maps following that, and the word is recorded to describe the area even earlier than that (though not in map form.
If thats what the animation says then I can tell you its complete BS... we know quite well that historically there were states called pallestine .. i mean we have maps with it literally printed on it. and plenty of historic references to palestine...
Is your question what year was the first year we have recorded history of a land called pallestine?
So I spoke of "most plants" there is no one rule... There are a few common mechanisms that can be at play for plants:
* length of day
* Temperature
* inter tree communication
There are probably others I'm not thinking of.
Each plant cares about different things. For example cannabis cares **only** and length of day. So if thats all you control its all you need to get them to flower. This is typical of plants that can grow in the tropics where it doesnt get cold.
Non-coniferous trees are a bit more complex, they use a mix of signals including intertree communication, temperature, and length of day. To they may trigger later in the season if its a warm season.
Largely the difference from season to season with trees is due to temperature.
@SpaceLifeForm The fact that they reflect green is somewhat interesting,and has some interesting consequences.
That said its response to red and blue is not usually how most plants can tell the season (there are some exceptions). Most plants detect the season based on the length of daylight not its color.
However plants do respond to red and blue light in very interesting and different ways.. many plants respond to blue light be decreasing inter nodal distances for example.
@volkris I watched season one and didnt come back for a while.. tried it again out of boredom and while season 1 sucked, and season 2 was enjoyable but had a few cringe moments... season 3 is amazing!
Thats because it is always peoples fault.. corporations dont have their own thought, so even then its people :)
I've started work on Cascadia 9.2, the third of our earthquake preparedness video games. If you're interested in seeing how the sausage is made, tune in to the PIGSquad Discord (http://discord.gg/pigsquad) at 1 PM Pacific on Monday, October 16. I plan to go for a couple of hours until I'm at a good stopping point.
