Tell us an interesting random fact you stumbled across (Part 1)

Subaru are cars, but not all cars are Subarus. Cognac must come from the Cognac Region in France and meet certain standards. This is a Protected Mark, and only brandies that meet the standards may be called “cognac.”

Spanish brandy is totally different and exactly the same. Armagnac beats them both hands-down.

Interesting. I assumed that in the old days everything was done while watching the video.

That trombone thing seems so uniform…I guess they just played the sped up recording each time? And I wouldn’t have guessed putting a cymbal on the snare head would have made that sound (where Tom is hitting the brakes to stop).

Some odd sound effects instruments here:

Down in Mexico is an entire neighborhood of 3D printed homes for impoverished families.

wow if that works structurally it would be great but someone would get it banned cause that could put the real estate market in dire straits

Given any finite positive integer, you can find that many consecutive numbers without a prime.

To be more precise, let n>1. Then the sequence (n+1)!+2 to (n+1)!+n+1 contains no primes.

For all k such that 1<k<=n+1, k divides (n+1)! and so it also divides (n+1)!+k. Thus, none of the n numbers from (n+1)!+2 to (n+1)!+k are prime.

For example, if n = 3, then the sequence this approach give is 26, 27, 28. 26 and 28 are both even and 27 is divisible by 3.

If n=1,000,000,000,000, then the 1,000,000,000,000 consecutive integers from 1,000,000,000,001!+2 to 1,000,000,000,001!+1,000,000,000,001 has no primes.

Note that (n+1)!+1 may or may not be prime. If it isn’t prime, then you have a sequence of n+2 consecutive numbers from (n+1)! to (n+1)!+n+1 with no prime.

I was just made aware of the Napier deltic diesel engine.
I am not a " car or engine " person so when I saw that I was impressed and also thought, " that looks like it wants to explode in an angry mess of flying metal "

Seems to me that the majority of real estate markets would have nothing to worry about due to the land there not being cheap enough for such projects to be economically feasible.

I had friends who were train spotters, who would blather on about locomotives called Deltics. I had no idea that the technology behind the name was so impressive.

It’s not real estate agents but building contractors and carpenters’ unions that have relentlessly opposed modernizing building codes that would allow for more prefab modular housing.

! That is exactly what i was going to say !

To support a training exercise Mighty Derringer, the federal government produced a fake newscast showing Indianapolis getting nuked.

Ethan Allen had a nephew named Heman.

And you just made me aware of it. That is fascinating!

Like most kids, I played 33rpm vinyl at 78rpm and thought it was funny. “Chipmunks!” Only it wasn’t just that the pitch was higher…the tempo increased.

Wikipedia says:

The Chipmunks’ voices were recorded at half the normal tape speed on audiotape by voice talent (on the 1960s records, generally Ross Bagdasarian Sr.'s own voice overdubbed three times, on the post-1980s records, studio singers) talking or singing at half the normal speaking rate. When the tape was played back at normal speed, they would sound a full octave higher in pitch, at normal tempo. The technique was by no means new to the Chipmunks. For example, the high- and low-pitched characters in The Wizard of Oz were achieved by speeding up and slowing down vocal recordings. Also, Mel Blanc’s voice characterization for Daffy Duck was Sylvester the Cat’s voice sped up to some extent. Now, the same effect is created digitally and in real-time with a pitch shift.

If you take a Chipmunks video, like “Time Warp” and slow it down, the pitch doesn’t change. By the way for those who haven’t discovered it…look across the bottom of the window in youtube, where the CC and so on are located. Click the gear and you get an option for speed. At .25x you might expect the Chipmunks to sound normal…but they don’t. Likewise with this sound effect. Oh well.

I guess you need a physical medium, like a disc or tape, rather than electronic.

I learned today that Ted Kennedy was expelled from Harvard his freshman year for having another person take a Spanish test for him. He left school for a few years (during which he served in the military) before returning to the school and eventually graduating.

ETA: the reason I learned it today, by the way, is that the story of the expulsion was reported by the Boston Glob on this day (March 30th) in 1962.

The VR video player I use has a slo-mo function that makes people sound drunk. I wonder what it would do for Chipmunks.

Yeah, YouTube decreases playback speed by slowing down the rate the digitized data is played; only analog recordings of the waveform shift the pitch when played back at reduced speed.

This isn’t correct. If it were, then sounds would be played at a lower pitch when played at a speed lower than 1X. Afterall, slowing down an analog record or tape just slows down the rate that analog data is being played.

YouTube is doing something more complicated, i.e. they are sampling short snippets of audio, analyzing for frequency content, and then playing exactly those frequencies for a short period before moving on to the next snippet of video.

Who was the first NBA player to shatter a backboard? I just found out and could not believe it:

“Throughout the history of basketball there have always been athletes with the size and strength to slam dunk the ball through the rim. However, the first NBA player to shatter a backboard, Chuck Connors (who would become far more famous as an actor), did not do so with a dunk. When playing for the Boston Celtics in 1946, Connors took a set shot during pregame warmups, hitting the front of the rim. Because an arena worker had failed to place a protective piece between the rim and backboard, the backboard shattered.” - Backboard shattering - Wikipedia

‘French Roast’ with coffee is merely a method of roasting. It tells you nothing of the quality of the bean.

In France, they roast the bean until it is almost burnt (they do everything different in France :wink: :slight_smile: ). It says that in a gourmet cookbook I have :slight_smile:
