Photon hits particle (space dust or whatever) energy is lost through other pathways etc, photon re-emmitted, photon now has lower energy.

i see no problem with this...
unless they're claiming to know that light has encountered no mass whatsoever from the point of initial observation to the point of observed "energy loss"

Probably not, in Africa in ages past they lacked the concept of "future", only "the present" and could plan ahead in the sense that they want to change the present.

concepts and sense of time differ from person to person, i dont think you can apply a universal like entropy to rationalize it.

of course, entropy guides biological function in many ways, so there is a relation, but not in the sense of a direct cause and effect IMO.

im sorry, what?

The pan is designed to not explode.

Although, old pans, either by design or age, will likely fragment (which can result in shards going everywhere, dangerous)

you've clearly never been to amsterdam

also, your argument is incorrect, comparing pot to smoking is legitimate because it is taking analagous causes of poor health and comparing in magnitude, wheras pizza and whatever have different sources of "poor health" and only compare one aspect of magnitude in a trivial manner.

there's also a tiny bit of chlorine gas, whats your point?

Cyanide is a poison, it binds tightly to enzymes in the citric acid cycle (dont quote me on this) meaning that those enzymes are essentially deactivated, tl;dr, too much cyanide = you cant produce ATP.

there was also no one with a degree in creationist science who claims the degree is bullshit, likewise, psycology.

oh yes its mr NOT NOT NOT again, who claims to know everything but knows nothing.

Also, because pseudo-science would take over.

it would be like "why dont all the police go on strike until people appreciate them"

well, for one thing, their duty demands that they dont do so

secondly, if they did go on strike, shit would hit the fan, nothing left to protect or get appreciation from.

Teachers have very high employment rates, doesnt make them appreciated in the least.

employment rates != appreciation.

PROTIPS

most people with retardation are sterile, or are sterilized from birth (mostly girls, as if raped, they do not have to bear a child).

I was watching this, and I realised to the layman and common joe how absurd all this would sound.

>sodium chloride tissue

ಠ_ಠ

no you all have it wrong!

the lightning is striking the earth UNDER the land.

so if it strikes twice, the first one is to hit the earth that we walk on, and the second one is to hit the earth(dirt) beneath it.

and i could go even further, i strikes individual molecules, and given that the number of molecules that comprise what we define as (dirt) is enormous, we wont be running out of lightning for quite some time.

also, the world is flat and you WILL BE KILL BY DEMONS.

its not perfectly rigid, zero point energy means intrisict vibrational energy = arises as variability in bonds between atoms even at 0k = not perfectly rigid.

>would be the best thing for science that could possibly happen.

i disagree, solving the oncomming energy crisis takes precedent.

and this is secondary education?
I learnt this shit in Uni (tertiary, 18/19 years old), shoulda just gone to the UK and saved myself these shitty uni fees.

Good god man, the more i look at these tests the more i think Australia is the land of derpy hurr.

but one of the questions is only answerable (unless you're a lucky guess) with the knowledge that bromine is a ortho-para director, im looking at it right now, how can they expect you to know it if its something you havent been taught?

>>1128918
well if the UK teaches more shit than Australia, i'd say its a better in terms of education right off the bat.
