In college we weren't allow to use calculators either. I just deep six'ed my last two slide rules. I couldn't see the lines so well and didn't remember how to use them anyway. I almost put them on eBay but figured no one would know what they were or what they were for. The Flat Brain will have to do whatever figuring I need to do.

@Kermit , since @Will Gilmore has graciously offered to supply a large quantity of this product, maybe the research could be focused on something more meaningful. I mean if we are at the beach and all. We've got all winter to figure out how to light up a caliper.

Now I get it. Y’all don’t have light this time of year in Canada, eh. Put me down for some research!

I still keep an old aluminum K&E on the boat in case the batteries on the calculator go down or an electric thing takes out electronics.. (ok that is a stretch, I just like it)
My good Dietzgen Teflon slider one is at home.

I had just got a brand new one, in its Leather Case, when slide rule class was cancelled and changed to FORTRAN programming. It is still unused.
Best use for the NEW rule ,I saw, was someone had it mounted in a framed box with glass on front.
Sign on glass said...

"Break glass in case of loss of power"

I still have a "pocket size one" but quit using it when everyone asked...
"What the heck is that?"

When I was in officer training, the Navy issued a cheap one with razor blades.
In a class of 88 officers, 4 knew how to use one.
We were in Navigational training test about "Vectors". The 4 pulled out the slide rules and finished the test 15 minutes early and were standing in the hall drinking a coke. [ we 4 aced the test]
We were swarmed by the others... "What the heck is that?"
So...
I made $10 [ todays would be ≈$50 as a percent of pay] a lesson to teach them. Lotta beer money then;)

Jim...

PS: We launched a man to the moon, they used slide rules aboard Apollo since no battery power needed.

Caught me on that one. But, also, adding a "r" on the end like in, "I have a good idear, deah". Been out of NE since graduation in '69. My Bostonian Speak is a bit rusty.
BTW, what is this thread all about, anyway?:what:

this is a fair question. FACTS are different than opinions. i have read some that give facts that are in fact wrong/incorrect. instead of saying you are wrong and correcting them. it hurts feelings. can start internet fights. so, i chose this thread so all can discuss some facts and or just learn.
hull speed is a good example. seems few here understand what it is. once one learns and understands hull speed it can enhance many options of using these toys. just saying :)

FUN FACT: never let the facts get in the way of a good story

hull speed smull shpeed. What's important is getting to the Three Philosophers first. You'll need a slide rule (I bought one at an antique shop) and to be able to exceed hull speed. To find the beer and get there first.

BTW. There is a local brewery here called Shillings that makes great beer and flat bread pizza. Come and visit and I will buy 'cause I won't pay for shipping, @Kermit and @Meriachee.

PS. Lloyds of London rated insured ships by hull and equipment. A first class hull was an 'A' and the equipment was rated a '1'.

Yep and you were one of the people who understand "hull speed":clap:

Having sailed different boats surely doesn't qualify you in Fluid Dynamics and shape factors. Ever heard of a "gull wing hull"? How about "wave surfing" or current drag factors? Oh well...:)

So if a nautical mile is a minute of latitude what is a statute mile a measure of? for completeness a nautical mile is only a minute of longitude at the equator

hull speed is that speed that the bow induced wave and the stern induced wave the boat generates anytime you move it in the water are at the wavelength equal to the boat water line length. wave move a different speeds depending on their wave length. longer waves move faster which is why a bigger boat can go faster than a smaller one.
next question: why does the boat generate different wavelength waves at different speeds?

Thou speakest of ideal conditions about boat induced waves.;) [which are still good estimates of the real world under normal conditions]

The USS Enterprise CV-65 hull length would allow her to out run her escort vessels in a fleet emergency also the detection of a nuclear missile. She could be 20 miles away from an impact.
Jim...

PS: I am confused about your wave frequency [ point to point count of generated waves] or the length of each wave generated.;)

In southern language...

STATUTE = "Is that you?"

If your friend is named Miles then, in southern speech, when talking to Miles in the dark...
Statute Miles?

y'all want some Shrimp n' grits?
I'm headin' to git me some Three Philosophers. After consulting my slide rule, I'm tearin' up the hull speed limit.
This picture should splain how it's done.
