Response:
We have searched our holdings and the University's web site, but have been unable to uncover any details about the talk. You may want to contact the Center for American History on the UT campus. They are the University's archive. You may also want to contact the physics department.
I've sent an email to both the archive and the physics department.

Thanks for making the effort Mike.
From my searches I cannot find any record of him lecturing on anything other than rockets. Face it, he was a famous person who could lecture on rockets - which were, of course, a VERY hot subject at the time. So why would anyone ask him to lecture on a subject that he would have been fairly ignorant of. I say ignorant because he was excluded form any American nuclear research and had no real contact with anyone doing such research. Although the cyclotron was invented in 1929 I doubt he would have really known much about them - certainly not enough to have warranted a lecture on them. Then we have the claimed subject "The Half Life Of U235 In A Cyclotron", how much more ridiculous can it get?

And, a Google search on the phrase "The Half Life Of U235 In A Cyclotron" gets NOTHING BUT this thread. Ditto for "U235 In A Cyclotron".

Don't get your hopes up. Universities are notorious for keeping bad records. There may indeed be no record and the event might well have happened.
Your best bet is either the university archives or the archives of the Austin paper(s).

* In the same sense that Suzanne took a class from Von Braun, I once took a class at Stanford from J. Robert Oppenheimer.
It went like this: The word came around in our lab, which was a mile or so off campus in Menlo Park, that Oppenheimer was on campus and giving a lecture at 2:00 in the big lecture room in the Physics Hall. A bunch of us biked over and found the place teeming with the curious. We could barely stand in the back door and see the stage. The room seated about 150 and there were at least 300 people there.
Oppenheimer was introduced (by Felix Bloch*, as I recall). He seemed very appreciative of the crowd as he opened his remarks, "There are probably about a dozen people here who will have any idea of what I am talking about."
We hung around for about ten minutes and then went back to work.
earle * PS: Felix Bloch shared a Nobel Prize with Edward Purcell (Harvard) for the discovery of nuclear magnetic resonance. I did take a class in Nuclear Physics from Purcell -- a one-quarter lecture class when he was a visiting prof at Stanford -- I made an A.

Well, knowing how to use your tools is sort of a pre-requisite for attempting to prove a negative using those tools.
For instance, a google search for
u235 cyclotron half-life von-braun
gets around 1400 hits, lots of them false positives, but at least one of which informs us that von Braun was student to a professor well known for using the half-life of uranium to do useful mineral dating to estimate the age of the earth, and several of which place cyclotrons in Germany well before WW-II.
It's pretty much impossible to study under a professor and learn nothing about that professor's particular hobby horse subject.
It's thus unlikely that von Braun, as a member of the German scientific community, would have absolutely nothing, ever, to say either about uranium half lives, or about cyclotrons.
Cyclotrons would have been useful research instruments, for example, in Germany's putative war-time atomic bomb research, so von Braun could have been called in to talk bomb program scientists and staff about, oh, say, missile throw weights versus atomic bomb design weights, or whatever.
> Suzanne, as usual, is a willful idiot *and* a > shameless liar.
Well, yes, she is, in the general case, but you've come nowhere close to exercising the due diligence needed to prove your case against her in this particular discussion.
FWIW
xanthian.
Sort of as an aside, for conspiracy theorists, this piece of "speculative" history might suggest a whole lot more that scientists in the German war effort would have had on their plates for consideration and gossip.

Starts with the first two results being this thread. It provides NO articles or citations that connect VB with either U235 work, or cyclotrons, never mind BOTH...

Try ALL of them being false positives, aside from two for this thread.
If you wish to suggest that there was a true positive, please post it.
Otherwise, you're trying a Fallacy of Proving a Negative.

But, with nary a connection between the two topics.

Sure. But, it is not logical to state that someone like VB would speak on such a fast moving topic, when his ONLY possible qualification would then be at least 20 years *out of date*.
> It's thus unlikely that von Braun, as a member of > the German scientific community, would have > absolutely nothing, ever, to say either about > uranium half lives, or about cyclotrons.
No, on the basis of being able to speak about either topic by the late 50s, it is highly unlikely, because his possible knowledge on either topic, never mind on a combination of the topics, would have then been at least 20 years out of date, in a field where the state of the art was moving amazingly fast.
One might as well expect a designer of the prop fighter ME-109 to give a talk to designers of the supersonic jet fighter F-104... Ain't gonna happen.

That's also greatly unlikely, as his only expertise in that area would have been for the V-2 (Then, 15 plus years out of date.), or the tactical Redstone missile. VB had zilch to do with ANY US ICBM or IRBM project at that time. So, he had the same qualification, zilch, to speak about ICBM and/or IRBM capabilities. Never mind zilch quals to speak of the buckets of instant sunshine nuke payloads...

As I have explained above, yes, I have.
Further, there is simply NO record of ANYONE having given a talk on the half life of uranium *in a cyclotron*, period.
As Suzanne is the positive claimant about that, The Burden Of Proof is all HERS.

Or they could forget about it. There's no conclusive way to prove this negative. As it is they're merely disputing the ancillary views of a war criminal.

If you think about it, that would be physically impossible, as the posting would have to exist somewhere in a news spool and have a URI before a tinyURL pointer to it could be constructed, and yet that pointer was already _in_ the post.
Of course, when I just checked that preview tinyURL again, it points exactly where it was supposed to point.
As I said earlier, you need to learn to use your tools, not just let them mislead you into making a public fool of yourself.

I'm not going to justify that swill you posted with a point by point rebuttal. If you insist on remaining deliberately ignorant, are so mind-blind that you introduce conditions into events that had no reason to be affecting those events, and are not literate enough to read what I wrote intelligently, nor literate enough to review search results intelligently
[Of _course_ the most precise hits the search found are to this thread. Do you ever bother to _think_ before you type?]
which your responses confirm to be the case, me writing more is a waste of my time. YOU read what you wrote above (including several deliberate lies) and see all the places you have (again, if I recall) made a public laughingstock of yourself.
Then again, if you can't read what I wrote, why should you be able to read what you wrote?

Oh, and just to give your unjustified smugness that you _must_ be correct a bit of a nudge, remember that isotope decay rates slow as radioactive particles approach the speed of light, and then read the "Plasma Separations" paragraph here:

The cyclotron having been invented by Lawrence around 1929-30, that's not too surprising. Once Lawrence built one, everyone would have wanted one.

That doesn't explain Suzanne's muddled mention of the half-life of uranium in a cyclotron. If it all generally happened as she says (and I think the argument over whether it was a class or a lecture is pretty pointless) it would appear she may not have understood it and it has now been passed through the defective memory filter of things not well understood. Perhaps Braun had some reason to mention cyclotrons and some reason to mention uranium, but I simply don't believe he talked about half-life in cyclotrons.

Well, no. A calutron (http://en.wikipedia.org/wiki/Calutron) is a form of mass spectrometer used to separate out U isotopes. The beam of atoms travels at well below the speed of light in the plasma gas; if the beam approached the speed of light (something that would take an extraordinary amount of energy given the quantities of plasma involved), the trick of bending the ions in a magnetic field just wouldn't work. And given that the half life of U235 is 700M years, I really don't understand how you might be able to measure the difference. Given U235 at just subluminal for a *year*, the difference in half-life would be a vanishingly small number of the order of 1 in 10^-8. The path length in the average calutron would be measured in micro seconds.

Both fact are very true. However, the use of uranium in dating has nothing whatsoever to do with a cyclotron.
WvB would not have had anything to do with nuclear matters once he started working on the military rocket programme.

True.

Why would he?

Possible, but in reality it would have been the other way round if there had been contact, which there wasn't, they would have been telling him how big a rocket they needed.

Rubbish, case proven long ago.
One of my main points being that once in the USA WvB would not have been allowed within a mile of any nuclear secrets.

And I see little reason von Braun might have talked about such an arcane factoid. One wonders if vB had even heard of a calutron...

> u235 cyclotron half-life von-braun
It is absolutely possible that Suzanne heard such a lecture. Why someone would talk about it is another question since the half life of U235 is rather high and near light velocities would have to be obtained to make any significant difference in or out.
In general however Suzanne is always wrong, especially when talking about science. Light does not slow down so you can hear it. (Part of a longer equally bad explanation) Ripples from a stone toss into water move in a radial pattern, not orbital. These are only the ones I remember but there are a large number of them. When she started she often would post references. Reading those references always showed that her conclusions were not that of the writer. Given two conclusions drawn from the same data by the same person, she will deny one and accept the other with no other reason than "because". She needs nothing other than what she would like to be right. "I don't know what others think, but I can tell you that I feel an inner confirmation that it is the truth, so I don't need outside archaeological evidence to prove to me that it is true."
Suzanne does this all to "prove" the bible is absolutely correct.
Her statements have reached the point where truth is an extraordinary event and demands extraordinary evidence to support it.

Good timing., this just came in."I looked in our subject file for the University of Texas Department of Physics, which consists mostly of clipped newspaper articles from throughout the 20th century that feature the Department, but I did not find mention of the von Braun talk there."

Who needs "not well undstood"
I spent at least 40 years with secure knowledge of something I remember learning in an excellent high school physics class in the 57/58 school year. I was wrong when I looked into the subject a few years ago. Interesting the wrong part of it was probably there by the early 60's at least. (And the 60's didn't start in the early 60's.)

True but if they provide evidence that he was there in that time period and talked about rockets, it would imply that she was wrong again.

Sure, but isn't that beating a long-deceased and decayed horse? it's you own business, but why bother? She's just pathetic. I suppose, though, that could go for any individual creationist.

Well, as I noted elsewhere, spinning U235 in cyclotrons was a well known technology to separate concentrations of it from U238, so he could have talked about U235 in cyclotrons.
Spinning U235 in a cyclotron has two effects on its half-life.
1) It lengthens the half life by slowing down time for the U235 from the viewpoint of the external observer. This is probably a trivial effect, what with the half-life of U235 in isolation being around 700,000 years, if I recall correctly, and its time in the cylotron probably being less than a minute.
2) It shortens the half life by concentrating U235 so that "in isolation" is no longer the case.
This is a non-trivial effect.
A critical mass of U235 has a half-life measured in fractions of a second plus a very big boom.
Other, smaller size concentrations, such as might occur in cyclotrons at the target location for acquiring the concentrated U235, would range in half life from that short one to the long half life in isolation.
Therefore, considering the half-life of U235 in a cyclotron is in fact a valid engineering concern.
You don't want too much of it in any one place, or you increase your radioactive contamination due to fissioning U235, and decrease your product yield.
There is therefore no particular reason von Braun either would be unaware of that concern, or that it would be surprising for him to mention it, in an off-handed way in passing, in a public lecture, long after the basic science was declassified.
Insisting that such an event _could not_ have occurred shows an ignorance both of history and of basic science.

That has no affect on whether von Braun might have mentioned U235 in a cyclotron and its half life, though.

That certainly would not have been the case in Germany, may well not have been the case in the US if he were working on ICBMs.

We can't read his mind, nor make his decisions for him; personal whim, showing off, making a point in his lecture are a few of uncountable possibilities.
"Why would he" is a useless argument and a useless rebuttal.

Well, no. He could just as easily have been being consulted on the issue "how small a bomb do we have to build". Designing a new, bigger throw weight rocket is a non-trivial time consumer also (initial V2s had a horrific failure rate), and Germany was in a time crunch to get a weapon of mass destruction to prevent their homeland from being overrun.
Later, in the US, if he were working on ICBMs, exactly the same reasons for the bomb designers consulting him would have held sway.

Not so far, IN THIS PARTICULAR DISCUSSION.
Merely declaring a win is nowhere nearly so convincing as is winning.
You've got a long way to go to convince _me_, for example, because as a former nuclear weapons handler and maintainer, I got a rather excellent general education in all things "nuclear weapon".
So far, most of the arguments against the possibility of WvB having made the statements Suzanne recalls hearing have been of the null quality of your "why would he" above -- people arguing from gut feelings rather than from facts.
To disprove that he _could_ have made such a statement, you have to give the widest latitude to reasons he _might_ have been able to make the statement.
So far, that hasn't been the case at all.
Arguments that a leading respected scientist _could not have known_ some basic cyclotron science facts are garbage, for example.

What he learned doesn't much have to have been secrets, it's just basic science, known around the world before WW-II began, and also doesn't have to have been learned in the US; the information was there to learn while he was working in Germany.
xanthian.
Notice that I'm not arguing that Suzanne _did_ hear any such thing from WvB under _any_ circumstances. Suzanne is far past senile, and she has long ago suffered a severe disconnect from reality that affects everything she says.

A final response After having done searching to try to answer your question, I’m sorry to say that it appears I cannot offer a confirmation of von Braun having spoken here in the 1950s or 1960s at this time.
I checked our physics and engineering departments’ subject files, and did not find mention of his speaking on campus. I did find one article from the engineering department file that described the opening of the 1966 school year’s lecture series in the department, which was to feature space scientists, but it did not mention von Braun specifically and no follow-up articles were included.
I called the physics department office and its library, and neither could confirm a record of such a talk. The email response I later received from the physics librarian did note that it is certainly plausible that he spoke here, and she included a link to a scanned page in Google books that mentions a 1950s speaking tour through Texas in which he especially focused on college students who might be recruited to his program. You can find it here: http://tinyurl.com/yg5rkta She also gave me the name of an aerospace engineering professor who joined the department in 1960 and who is still here, and I emailed him to ask if he might know anything about the talk, but I have not yet received a reply. I will let you know if he writes back.
I searched through our UT Student Publications negatives and photograph proofs collection to see if there might be photos from the event, if it was covered in our yearbook or student newspaper, but did not find any.
My best guess for additional resources here on campus would be issues of the student newspaper, the Daily Texan, where there might have been a write-up. Unfortunately, we do not have digitized archival issues of the paper, so I cannot run any kind of search for the event. All back issues are on microfilm, and due to staff constraints, I cannot look through all of the coverage for that time period to find a mention of von Braun speaking on campus. There are proxy researchers that you could hire to do it for you, since you are located distantly (see http://www.cah.utexas.edu/services/proxy_researcher.php).

Since Von Braun worked on the American ICBM program before joining NASA, I don't think that dog will hunt.
Besides, between 1950 and 1956, von Braun led the Army's rocket development team at Redstone Arsenal, resulting in the Redstone rocket, which was used for the first live nuclear ballistic missile tests conducted by the United States.

VB never worked on any ICBMs. The Redstone was not even an IRBM, rather it was a battlefield weapon, with a range barely greater than that of the V-2.
Further, given the great secrecy over matters of nuclear technology, just because a guy worked on one small delivery system for such payloads, in no way indicates that said guy would be allowed any information about the payload, other than basic size and mass.
