Tell me again how the cold atmosphere warms the surface?

No.13696728 ViewReplyLast 50OriginalReport
Yup, back to this question which never seems to get answered. Yes yes, I get responses like "it's not reversal of entropy, it's energy that takes less time to leave thus increasing an accumulation of energy which adds to the current temperature"

Is that right? Isn't that was is said? So how come my cold fridge can't impart its energy into the open oven? What if I put little LED bulbs inside my fridge and use the light from them to "add to the current temp of the oven" seeing that's all co2 emits, light. Right? Co2 doesn't emit 'heat' just photons of light. Which is also an intensive property btw.

So, please, can someone explain why the cold atmosphere returning back light to the ground, adding 'heat' to the surface is not a violation of entropy but my cold freezer/oven analogy is?

Racial IQ.

Do believe that this place role in our modern lives today?

What is your opinion on about races that are intellectually superior?

Should lower IQ individuals be treated as less than?

Do think believe that racial IQ should be made aware to the public?

Quantum entanglement

Scientifically, how do we explain the fact that I can simulate a Bell's inequality violation using a simple model of a photon and polarizer?

from collections import defaultdict
from random import seed, choice, uniform
from math import sin, cos, pi
import numpy as np
import matplotlib.pyplot as plt

class Photon:
def __init__(self):
self.angle = choice(range(360))

class Polarizer:
def receive(self, photon):
threshold = sin((photon.angle/2)*(pi/180))**2
return 1 if uniform(0, 1) < threshold else 0

def run_trial(angle):
polarizer = Polarizer()
photon = Photon()
return polarizer.receive(photon), photon.angle

def test_bell(count):
test = count[45] > count[22] + count[23]
relation = ">" if test else "<"
print("%f %s 2 * %f = %f" % (count[45], relation, count[22], count[22] + count[23]))
return test

def run_experiment():
seed()
count = defaultdict(int)
for angle in range(360):
for _ in range(NUM_TRIALS):
r, theta = run_trial(angle)
count[theta] += r

for angle in range(360):
count[angle] /= float(NUM_TRIALS)

print("Bell's inequality violated?", test_bell(count))
return count

def plot_results(count):
fig, ax = plt.subplots()

plt.title("Experimental Results")
plt.xlabel("Angle (degrees)")
plt.ylabel("Probability")

x = np.arange(0, 360, 1)
y = count.values()

ax.plot(y, color='black', label='Polarizer')
plt.ylim([0, 1.05])
plt.yticks(map(lambda x: float(x)/10, range(11)))
plt.legend()
plt.show()

if __name__=='__main__':
NUM_TRIALS = 10000
plot_results(run_experiment())

Oxygen damage and apnea inmortality

Is there any model of cellular aging where holding your breath a lot and breathing very shortly/nose breathing, results in stopping aging?
I know you die without breathing,but for example if a yoga master holds his breathing 20 minutes per hour(total)would he live to 120 without senility?
