Shocking 1950s Commercial
Actually, whether or not the dust was dangerous would depend on what sort of emitter it is (alpha particles, beta particles or gamma rays), how quickly it was emitting and whether the actress inhaled the dust or it was just on her skin. For example, alpha particles can only penetrate a few cells deep when attempting to pass through skin but if she inhaled something that was giving off alpha particles then she would be in some serious hot water.

How to Photograph the Earth from Space
Interesting info:
The colourful dots you see all over the shot at the start as he is talking, are pixels in the CCD of the camera that have been hit by radiation from space!
The pixels have been exposed to energetic particles with such intensity that they no longer see a gradient between light and dark, its all light....the pixel has been 'saturated' to the point of damage.
The detail is best seen in full screen @720p. You wont see them in the lower-resolution streams.
The Phone Call
True but the Atheist also holds the "belief" that there is not GOD. So which belief is more correct? For me to get into a biblical debate with you and the atheist sift community would be pointless. It's like the saying you can bring a horse to water but you can't make him drink. So this makes me search the web for other ways to argue the point. Here is 1 of them.
Mathematically speaking evolution falls flat on it face..

Suppose you take ten pennies and mark them from 1 to 10. Put them in your pocket and give them a good shake. Now try to draw them out in sequence from 1 to 10, putting each coin back in your pocket after each draw.
Your chance of drawing number 1 is 1 to 10.
Your chance of drawing 1 & 2 in succession is 1 in 100.
Your chance of drawing 1, 2 & 3 in succession would be one in a thousand.
Your chance of drawing 1, 2, 3 & 4 in succession would be one in 10,000.
And so on, until your chance of drawing from number 1 to number 10 in succession would reach the unbelievable figure of one chance in 10 billion. The object in dealing with so simple a problem is to show how enormously figures multiply against chance.
Sir Fred Hoyle similarly dismisses the notion that life could have started by random processes:
Imagine a blindfolded person trying to solve a Rubik’s cube. The chance against achieving perfect colour matching is about 50,000,000,000,000,000,000 to 1. These odds are roughly the same as those against just one of our body's 200,000 proteins having evolved randomly, by chance.
Now, just imagine, if life as we know it had come into existence by a stroke of chance, how much time would it have taken? To quote the biophysicist, Frank Allen:
Proteins are the essential constituents of all living cells, and they consist of the five elements, carbon, hydrogen, nitrogen, oxygen and sulphur, with possibly 40,000 atoms in the ponderous molecule. As there are 92 chemical elements in nature, all distributed at random, the chance that these five elements may come together to form the molecule, the quantity of matter that must be continually shaken up, and the length of time necessary to finish the task, can all be calculated. A Swiss mathematician, Charles Eugene Guye, has made the computation and finds that the odds against such an occurrence are 10^160, that is 10 multiplied by itself 160 times, a number far too large to be expressed in words. The amount of matter to be shaken together to produce a single molecule of protein would be millions of times greater than the whole universe. For it to occur on the earth alone would require many, almost endless billions (10^243) of years.
Proteins are made from long chains called amino-acids. The way those are put together matters enormously. If in the wrong way, they will not sustain life and may be poisons. Professor J.B. Leathes (England) has calculated that the links in the chain of quite a simple protein could be put together in millions of ways (10^48). It is impossible for all these chances to have coincided to build one molecule of protein.
But proteins, as chemicals, are without life. It is only when the mysterious life comes into them that they live. Only the infinite mind of God could have foreseen that such a molecule could be the abode of life, could have constructed it, and made it live.
Science, in attempt to calculate the age of the whole universe, has placed the figure at 50 billion years. Even such a prolonged duration is too short for the necessary proteinous molecule to have come into existence in a random fashion. When one applies the laws of chance to the probability of an event occurring in nature, such as the formation of a single protein molecule from the elements, even if we allow three billion years for the age of the Earth or more, there isn't enough time for the event to occur.
There are several ways in which the age of the Earth may be calculated from the point in time which at which it solidified. The best of all these methods is based on the physical changes in radioactive elements. Because of the steady emission or decay of their electric particles, they are gradually transformed into radio-inactive elements, the transformation of uranium into lead being of special interest to us. It has been established that this rate of transformation remains constant irrespective of extremely high temperatures or intense pressures. In this way we can calculate for how long the process of uranium disintegration has been at work beneath any given rock by examining the lead formed from it. And since uranium has existed beneath the layers of rock on the Earth's surface right from the time of its solidification, we can calculate from its disintegration rate the exact point in time the rock solidified.
In his book, Human Destiny, Le Comte Du nuoy has made an excellent, detailed analysis of this problem:
It is impossible because of the tremendous complexity of the question to lay down the basis for a calculation which would enable one to establish the probability of the spontaneous appearance of life on Earth.
The volume of the substance necessary for such a probability to take place is beyond all imagination. It would that of a sphere with a radius so great that light would take 10^82 years to cover this distance. The volume is incomparably greater than that of the whole universe including the farthest galaxies, whose light takes only 2x10^6 (two million) years to reach us. In brief, we would have to imagine a volume more than one sextillion, sextillion, sextillion times greater than the Einsteinian universe.
The probability for a single molecule of high dissymmetry to be formed by the action of chance and normal thermic agitation remains practically nill. Indeed, if we suppose 500 trillion shakings per second (5x10^14), which corresponds to the order of magnitude of light frequency (wave lengths comprised between 0.4 and 0.8 microns), we find that the time needed to form, on an average, one such molecule (degree of dissymmetry 0.9) in a material volume equal to that of our terrestrial globe (Earth) is about 10^243 billions of years (1 followed by 243 zeros)
But we must not forget that the Earth has only existed for two billion years and that life appeared about one billion years ago, as soon as the Earth had cooled.
Life itself is not even in question but merely one of the substances which constitute living beings. Now, one molecule is of no use. Hundreds of millions of identical ones are necessary. We would need much greater figures to "explain" the appearance of a series of similar molecules, the improbability increasing considerably, as we have seen for each new molecule (compound probability), and for each series of identical throws.
If the probability of appearance of a living cell could be expressed mathematically the previous figures would seem negligible. The problem was deliberately simplified in order to increase the probabilities.
Events which, even when we admit very numerous experiments, reactions or shakings per second, need an almost-infinitely longer time than the estimated duration of the Earth in order to have one chance, on an average to manifest themselves can, it would seem, be considered as impossible in the human sense.
It is totally impossible to account scientifically for all phenomena pertaining to life, its development and progressive evolution, and that, unless the foundations of modern science are overthrown, they are unexplainable.
We are faced by a hiatus in our knowledge. There is a gap between living and non-living matter which we have not been able to bridge.
The laws of chance cannot take into account or explain the fact that the properties of a cell are born out of the coordination of complexity and not out of the chaotic complexity of a mixture of gases. This transmissible, hereditary, continuous coordination entirely escapes our laws of chance.
Rare fluctuations do not explain qualitative facts; they only enable us to conceive that they are not impossible qualitatively.
Evolution is mathematically impossible
It would be impossible for chance to produce enough beneficial mutations—and just the right ones—to accomplish anything worthwhile.
"Based on probability factors . . any viable DNA strand having over 84 nucleotides cannot be the result of haphazard mutations. At that stage, the probabilities are 1 in 4.80 x 10^50. Such a number, if written out, would read 480,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000."
"Mathematicians agree that any requisite number beyond 10^50 has, statistically, a zero probability of occurrence."
I.L. Cohen, Darwin Was Wrong (1984), p. 205.
You are wrong...you are confusing something that you "believe" and stating it as a "fact".

Physicist Sean Carroll refutes supernatural beliefs
Forces and particles don't exist as much as they are an observation. Lets not figure out why we think there are particles or forces. That could never lead to something useful.
Matt Dillahunty - We Are Atheism Interview
Ok, Matt ... you determined that scripture and theology did not sufficiently answer the questions you were asking. Is there another set of beliefs which does? What is the source of any knowledge that you have? Have you yourself tracked a quantum particle/wave. Or have you even watched a paramecium under a microscope and wondered why it "swims".
If you can't devise a belief structure which accounts for the observed behavior of the universe, then you are ultimately bound by descriptions given by others. And if you cannot refute their given explanation based on observable phenomena, you have only wishful thinking to support your beliefs.
Incredible Space Saving Furniture
I rather have my nice, large, solid-wood, comfy, king-sized bed with a high end tempur-pedic mattress, my handmade armorie, and a nice, solid wood desk. Sleeping on cheap-particle board and foam as an adult seems like the most useless idea to me.

Yeah. They forgot to address the whole, "It's a wave AND a particle" problem.
What Is Light? Young's Double Slit Experiment
It also leaves you with the impression that light is a wave and not a particle. In truth, it depends on the circumstances and who's looking.
Nice, but the video doesn't address the best part: the effect of observation.
