Don Herbert died this weekend. For a couple of generations of American, he was TV’s Mr. Wizard doing simple science experiences that kids can understand. Here is a clip of Herbert and a student. He is putting a flame to fake money that is wrapped around a metal bar, but the money would not burn.
Yeah, but you know why? ’cause it has this in it.
Why? What is it?
Metal object.
That is a good conductor and it will take the heat from the flame before the phony money has chance to burn.
What kind of heat conduction convectional radiation is it?
It would be conduction.
Conduction! Now in other words, the heat from the candle goes to the paper and is pulled away so fast by the metal bar. That keeps the paper from burning because it can not get up to the high temperature.
Yeah, I think it is true.
Ok, then what would happen if you slowly pull out a mental bar out of there.
Well, that will be no conductor behind so it burn out.
All right, Try it.
There goes. Burning out.
A national science foundation official once said of Herbert. Over the years Don has been personally responsible for more people going into science than any other single person in this country.

听起来觉得和大家不太一样的我画线了，不知道对不对~

Don Herbert died this week. For a couple of generations of American, he was TV’s Mr. Wizard doing simple science experiences that kids can understand. Here is a clip of（这是什么意思啊？） Herbert and a student. He is putting a flame to fake money that wrapped around a metal bar, but the money won’t burn.  

S：Yeah, but you know why? ’Cause it has this in it.

H：Why? What is it?
S：Metal object（老实话，怎么也听不确切，看完大家的，好像有那么一点意思）.

H：What is it? Metal object...
S：That is a good conductor; it will take the heat from the flame before the phony money has chance to burn.
H：What kind of heat conduction convectional radiation is it?
S：It must（怎么听都像was，汗，但又没道理） be conduction.

H：Conduction!

S：Ahem~

H：In other words, the heat goes through the paper and is pulled away so fast by the metal bar that it keeps the paper from burning because it can not get up to the high enough temperature?
S：Yeah, I think it is true.
H：Ok, then what’ll happen if you slowly pull that mental bar out from there？
S：Well, there will be no conductor behind it ( H：yeah~) so it’ll burn up.
H：All right, turn out.
S：There goes. Burning up.

这个是不是周末没有？

(S) Yeah, You know why?’cause it has this in it?
(H) What’s it?
(S) Metal object.
(H) What’s that Metal object?
(S)That’s a good conductor that take heat from land before the phony money has tend to burn
(H) What kind of heat conduction convectional radiation is it?
(S) That is conduction.
(H) Conduction.Now in other word, heat  from candle goes to paper. and it is pulled away so fast by the metal bar, that keeps the paper from a burning, because it can not get up to high temperature.
(S) Yeah, I think it is true.
(H) OK,Then what would happen if you slowly pull out that metal bar out from there?
(S) Well, That would no conduct behind so it would burn up.
(H) Try it.
(S) There it goes. Burning out.
A National Science foundation official show off that over years Don has been personal responsible for more people going to sciences than any single person in this country.

Television's "Mr. Wizard," Don Herbert, who taught generations of children about science, died at his Southern California home Tuesday. He was 89.

From 1951 through 1964, Watch Mr.  ...

clip有剪下的意思。这里名词是剪辑：从电影胶片或录相带剪出的片断.:)

Here is a clip of Herbert and a student. He isputting a flame to fake money that is wrapped around a metal bar, but the moneywould not(won’t) burn.
Yeah, but you know why? ’cause it has this in it.

Metal object.

What’s that Metalobject (get to work)?
That is a good conductor and it willtake the heat from the flame before the phony money has chance to burn.
What kind of heat conduction convectional radiation(conduction,convection or radiation) is it?
It would(It’ll) be conduction.
Conduction! Now in other words, the heat from the candle goes to(through) the paper and is pulled away so fast bythe metal bar that keeps the paper from a burningbecause it can not get up to the high temperature?
Yeah, I think it is true.
Ok, then what would(will) happen if you slowlypull out a(that) mental bar out of(from) there.
Well, that will be no conductor behind so it(it’ll)burn out(up).
All right, Try it(try on试验的意思).
There goes. Burning out.
A national science foundation official once said of Herbert, “over the yearsDon has been personally responsible for more people going into science than anyother single person in this country.”（注意断句）

备注：
Conduction is the process of handing on energy fromone bit of stuff to the next, rather like a message in a letter being handedalong a line of students from one neighbor to the next.
Thermal convection
Energy can be carried by wholesale movement of the medium: a warmer fluidmoves, displacing a colder fluid thus transferring thermal energy in convectioncurrents. This is rather like a student carrying a message in a letter toothers rather than just passing it on down the line, as is the case withconduction.
Radiation is quite different from conduction and convection. Itis not a matter of something hot carrying the energy itself, or of atomshanding the energy on from one to the next. Hot things produce electromagneticwaves and so they cool down unless we keep on supplying them with energy. Whenelectromagnetic waves hit something then they normally warm it up.

弱问一下，大家都在这个网站http://www.sciam.com/听的哪个部分音频啊？
是video里的都听么？
这些听写都是哪个部分的？
刚来，不太懂！也想加入听写的队伍，请高人指导！！
谢谢！

What do airport baggage screeners, students andbasketball players have in common？They allneed a good night sleep. A study presented this week at the annual meeting ofthe Associated Professional Sleep Societies suggests basketballers who get someextra zzzs(ease), a are  more likelyto score in a game. Stanford University's researchers monitoredmembers of the schools men's basketball team during two weeks of regular sleepcycles, and then two weeks with extra sleep. With the extra sleep the athletes reportedincrease (increased) energy, faster sprinttimes and better free-throw shooting. Another study found that college studentswho pull all-nighters to prepare for tests tend to have lower grade-pointaverages than those who get regular sleep. And second and third graders withsleep disorders are more likely to receive bad grade (grades)in math, reading and writing according to a study from Chappaqua Public Schoolsin New York.But it gets even worse, a researcher from Brigham and Women’s Hospital in Boston found airportbaggage screeners who didn't get enough sleep made more errors in searching forunusual items that might be a threat. So you see you need to catch zzzs(ease) to catch bad guys.
