Regarding 13:35, Astronaut Buzz Aldrin used a Pickett Model N600-ES Five Inch Pocket Size Slide Rule for the Apollo 11 Moon Landing on July 20, 1969. His famous slide rule was later auctioned for $77,675 on September 20, 2007. Its original price was $10.95 in 1969.
I have just bought an N500 ES complete with box and paperwork in mint condition. I have to say I find my white Faber Castell 2/82 far easier to read. I like Pickett rules for their metal construction but find the term eye saver something of a misnomer. I also have a cased 2/82N which is the biggest slide rule I have ever seen. These things are addictive. Show a slide rule to anyone under 50 years old and they'll probably say "What's that used for?" What they won't know is that any engineering project pre 1970 was certainly built using slide rules. I say reintroduce their use in schools so today's kids will get a better feel for numbers. Thank you for a great video.
Teachers always told us, when I was a kid, that we wouldn't have a calculator in our pockets all the time. How wrong they were. If we didn't always have a very powerful calculator in our pockets, I would agree with you about teaching these to kids in school. As it is, the kids have got theirs in their hands almost all the time
I'm not a collector just a passing admirer. Very nice array of Picket slipsticks you have there. I like the yellow ones, easier on the eyeballs no doubt. I have a _Unique Universal II_ that my late father bought for 10/6 (10 shillings and sixpence) back in the 50's.
Working nights, didn't finish high school, traveled the world 40 years, and now learning algebra again with a slide rule.... Don't let the old man in!!
I happened to dig my N 1010-ES (yellow, 10" x 1.25", double-sided) out of storage recently, then came across your videos! Brought back good memories. I think my first slide rule was a plastic circular, then a plastic 6" straight, then finally graduated to the 'big leagues' with a metal slide rule. 😃
Addit: I got hold of a 1010 SL-T. That one has two square root scales (as on the K&E deci-lon), A, B, ST, T, S, C, D, DI and K on one side; L, DF/CF, CIF, C, D, DI and Ln scale on the other. Quite why they put the Ln scale on, I'm not sure, but it does perhaps compensate a little for the lack of log-log scales and it does allow direct reading of natural logs and powers of e within a limited range against both the D and DI scales. If I were redesigning this rule today, I'd change the K scale to the other side (there's still room for it if you push the L scale down a little) and replace it on the trig side with a P scale.
I just got my first slide rule, a Pickett 901ES, from a hamfest. No trig, like you said. I made a circular slide rule but this is my first commercially made slipstick.
They call the yellow version the "eye saver", but I have to admit I prefer the very pale beige T version better. I own examples of both. The 600 also has the Ln scale, which not that many others did.
jsm666 thanks for pointing out the ln scale (which the 800 does not have). I don't use these Pickett rules much! I also prefer the white versions, but as I pointed out the printing seems inconsistent on them.
@@ProfessorHerning I just got an earlier magnesium Model 600, and it has CIF instead of Ln. You can see both versions on ISRM. I prefer the earlier version too!
I hope you can get your hands on and showcase a Pickett N515-t electronic engineering slide rule. It's an amazing special purpose slide rule. In addition to the basic scientific stuff, it can calculate resonant frequencies and reactances and the back is loaded with electronic formulae. The downside is the ln scale, which is pretty much useless and distracts from the log10 scale.
I just found the answer to this in an old Castell instruction manual. C is for direct conversion from diameter to area. Place the D's 1 on the c, then read directly from D to B to get the area.
I know this is an issue. I actually record these on my phone without any special equipment, and there is no focus lock function, but this summer I am going to look into it.

It is a damn shame that these fell into disuse as I believe they engaged peoples brains more than a calculator does .
I use them every once in awhile. I'm sure that no one is stopping you & you still have a choice to use one now.
I know its a year ago that you spoke...but...I totally agree 100% right there ✔

Nice review! Speaking of specialty slide rules, I have a small Pickett from the late 1950s; it’s a Model 700 intended for arial photography.
They call the yellow version the "eye saver", but I have to admit I prefer the very pale beige T version better. I own examples of both.
The 600 also has the Ln scale, which not that many others did.

It's interesting that the 600 omits CIF for ln. I can't say I use either very often, but I'd probably do it the other way 'round.

Where does the Pickett n-500-t fit in?
Does anyone know what the Log Log scale used for?
It's for computing arbitrary powers and logarithms quickly. For example, 2.15^1.7 or log_2(70).

I have a 'pi' on the logscale itself, and an 'e'; but what does 'c' mean??
I just found the answer to this in an old Castell instruction manual. C is for direct conversion from diameter to area. Place the D's 1 on the c, then read directly from D to B to get the area.
Please turn off auto focus.
