I agree completely with visionep. Milkmans points are just not true or avoidable.
Theres also the point of engines not being able to run Ethanol at all. Vintage cars for example.
In the end this bio ethanol is just another farce to make money, at a very high cost to... as always... the poor.
What this guy says in the video is just not true. Even with only E10, a higher priced gasoline will still give you better mileage (up to 10%). This is happening in Germany right now. Nobody is buying this ethanol crap because it simply isnt worth it. Not to mention because of the detrimental effects on people and cars.


Yes, some older cars do not run well with an ethanol blend, and some might take that to a point where they wouldn't run at all.

You say bio ethanol is a farce to make money (aren't all businesses?) and the cost targets the poor. That makes a good soundtext-bite but I don't see how ethanol production is particularly detrimental to the poor, at least not in any way that isn't heavily outweighed by other competitors. Care to elaborate?

About mileage: yes, any blend of ethanol will give lower gas mileage than pure gasoline. The point that I would suggest is that when you burn that gallon of gasoline, it isn't coming back. At least not for a few million years. We can/will keep on burning through oil for a while, but as we do so the prices will go up.

Right now, today, the market settles out so that in Brazil the cost per unit of distance traveled may actually favor gasoline; car owners "vote" at the pump. But I'm talking about the long term, in the future. Corn, or better yet switchgrass, grows back. Not in millions of years, *next* year. We're just a few years down the line from the initial introduction of ethanol and ethanol blends as a fuel. And yet already it is making a bit of competition with big oil.

If better alternative fuels come along (hydrogen fuel cells or whatever), I'll be open to them. But at this point ethanol seems like one that actually works, and has been working, in spite of the fact that it doesn't have a fully stable infrastructure yet.

yea I don't believe this global warming crap.

when I was in college we were taught about the solar cycles decades of warming and cooling and we are right on track.

lot the political correct morons wanna lump people who dont believe in global warming with religious or militia/conspiracy theorist just to demonize those groups to the public.

political correctness is the worst thing that has ever happened to this world and needs to be eliminated.


anyhow the kooky hair scientist on periodic table of elements doesn't believe in the global warming media propaganda either, we are in the earth's normal cycle of warming and cooling thanks to dear old Sol.

This video is from their "Periodic table of videos" channel, not their "Sixty symbols" channel.
The periodic videos are about chemistry but the sixty symbols videos are about physics and astronomy.

Though Ron Paul and a fire hydrant are both better candidates than the Kenyan, foolish Paul quotes like this:
"Government should never be able to do anything you can't do"
mean he hasn't got a prayer atheist invocation of the Periodic Table of Elements of being elected.


OK QM, because you fascinate me, I demand to know who you'll be supporting.

hmmm sorry found it a bit dull really... lots of talking, little to look at...
e.g. hamburger in acid for 3 hours seems to dissolve... a bit any way. But if you did a control with a hamburger in water for 3 hours you'd probably find the bread and mince starting to dissolve and fall apart anyway...


You are not the only one with a problem with the burger aspect of the video. Good thing there is another twelve minutes or so to fill up the rest of the time around the burger.

Here is the full video of that one I thought was really shitty, the Hydrochloric acid burger one ya posted. Boo to it, YAY to this one.

McBoinkens: think of hydrogen as having potential nuclear energy. In the same way that wood or paper has chemical energy, i.e.

C + O2 + activation threshold energy --> CO2 + additional energy given off

then, from a nuclear perspective,

H + H + activation threshold energy --> Helium + additional energy given off.

but in this case, the element hydrogen becomes helium not by changing or sharing electrons but by jamming two nuclei into one atom.

All elements have potential nuclear energy and if you pump energy in they get closer to iron on the periodic table. Higher-level elements give off additional energy when they undergo fission (e.g. uranium in power plants). Lower-level elements give off additional energy when they undergo fusion (e.g. hydrogen in a hydrogen bomb).

The only thing that you have to do is provide sufficient energy to overcome the threshold. That can be a very big amount, but if you harness it, you can use it to keep the process going in the same way that you can use a pile of wood to keep a campfire going because it generates its own heat. The sun essentially works like this.

Upvote for the handwritten periodic table in the background of the classroom.

I tried teaching the Periodic Table of Elements; Solids, Gasses & liquids; and Transparent, Translucent and Opaque.

It was fun for a while, then we moved on and didn't get bogged down.
I'm lucky, my kids seem to Straight A (Principal's List) students (Knock on wood).
I'd like to attribute it to their inquisitive nature, It might be that I've always liked answering their questions, or maybe I just got dam lucky!

...to hell with sports stats and teams, and in Canada, no one cares who the past Prime-ministers were!

Now is that periodic as in the periodic table or periodic as in periodic acid as in HIO4?

uhhhh, I have a periodic table of elements in my wallet from 96', ;laminated, fold-able, and easier to reference....3-d glasses with an I-Pad....fuck dudes, get real...ITS TOO GODDAMN BIG AND USELESS!!!

Girl....give it up, yer review makes me want to not buy a USED one atta thrift store.....

Wikipedia on Christian Friedrich Samuel Hahnemann - the inventor of homeopathy:

Hahnemann claimed that the medicine of his time did as much harm as good:

My sense of duty would not easily allow me to treat the unknown pathological state of my suffering brethren with these unknown medicines. The thought of becoming in this way a murderer or malefactor towards the life of my fellow human beings was most terrible to me, so terrible and disturbing that I wholly gave up my practice in the first years of my married life and occupied myself solely with chemistry and writing.[3]

After giving up his practice around 1784, Hahnemann made his living chiefly as a writer and translator, while resolving also to investigate the causes of medicine's alleged errors. While translating William Cullen's A Treatise on the Materia Medica, Hahnemann encountered the claim that cinchona, the bark of a Peruvian tree, was effective in treating malaria because of its astringency. Hahnemann believed that other astringent substances are not effective against malaria and began to research cinchona's effect on the human body by self-application. Noting that the drug induced malaria-like symptoms in himself, he concluded that it would do so in any healthy individual. This led him to postulate a healing principle: "that which can produce a set of symptoms in a healthy individual, can treat a sick individual who is manifesting a similar set of symptoms."[3] This principle, like cures like, became the basis for an approach to medicine which he gave the name homeopathy.

So, homeopathy is based on an idea from a man who thought that medicinal drugs in the late 1700 was potentially harmful. No shit. The understanding of chemistry and medicine is incomparable to today's sciences, the periodic table, a vital part of the basics of chemistry wasn't invented until nearly 100 years later. Belief that this kind of treatment is as effective, if not more than conventional medicine is beyond me.

I'd like to quote Dara Ó Briain "people say 'well, science doesn't know everything' - well science knows it doesn't know everything, otherwise, it would stop."

and

"Well herbal medicine, 'herbal medicine has be around for thousands of years', indeed it has, and the stuff that worked became, medicine"

Yeah thats a super lame report on an rather inconclusive study.

On an other note, I'm always so confused at why guys gush over Rebecca Watson. People say well she is cute because shes a science nerd and she is funny. But listening to the skeptic guide, one finds shes not really on the ball as far as science goes, she has about the same level of understanding as someone halfway through first year sciences at university.

Ive seen pictures on their web site of her with a periodic table shower curtain, but I would bet money that she doesn't half of the uses of it ( electronegativity, atomic radius). And as far as funny goes, she provides the most palm to forehead lame jokes than anyone else (not funny lame either). I mean, I know alot of girls who are much smarter and funnier, couldn't the skeptics have found one too?

I don't know, she is a good blogger, maybe I'm being too hard on her. Maybe sooner or later I'll see the light, but for now...
