Science is Cool

 Ever wonder how a transmission work? This vintage video makes physics seem pretty cool as it explains gears, levers, and  other features of physics.  The 1936 job does a much better job than all the Ted Talks, fancy graphics, and other new-fangled presentations.  Enjoy.

Now they use composite belts and plastic composite gears in Automatic Transmissions. Cars just got too damn reliable so they had to fix that.

This is part of a series, and yes, it's good.

Thanks Kingfish! Not only was that enjoyable and educational to watch but it brought back memories of my school days when such films were shown in the classroom. It was always a thrill to see the projector being rolled into the classroom.

Can't use the word 'shaft' any longer.

Agree with 4:48. Saw many of these type films in HS during shop, etc. Also got to set up projectors being part of the AV (Audiovisual) crew. Thanks so much for showing this. Know a few shade trees who would benefit from watching this and others like it.

It's a damn shame you can't hardly find a stick shift car or truck anymore.....nothing is as fun as a good four speed. I know the high performance cars can be bought with one but not your common jeeps, honda's, small trucks, etc. Everything is going front wheel drive, Constant velocity crap,

Human ingenuity will forever fascinate me. In a small way it makes me think back of my grandfather, WW1 veteran...as a youngster returned to Simpson county started farming and somehow managed a household of ten....eight boys!
That said...when your a broke farmer in the middle of a plow field and your machinery breaks...you figure out a way to fix it.

We've lost much of the focus of our creative genius away from making lives better to making a few richer. Hence we now have Bitcoin, credit default swaps, Facebook, and trial lawyers.

That's what used to be called "technology", and truly was. Today technology is computer programming - which has been hijacked and leveraged to create division among peoples or to sell stuff.

Nice posts except for the perpetual gripers at 5:07 and 6:35.

@7:02 You should take Honda off that list as they still make the accord in a manual trans. And also, the 'constant velocity' you speak of is for the joint on the axle, not in a transmission.

Most street crooks are unable to drive a manual transmission vehicle that even the illiterate could drive 80 years ago.

And most of today's educated youth can neither drive a stick shift nor understand how even a toilet operates.

It's really tragic.

Of course these days every 10 year old can program and use a cell phone app and bypass the parental control on all their electronics.

That's life I guess.

Try a 14-speed. Or one with 3 stick shifts.

Also, Jeep Wranglers come standard with a manual transmission; although as a 6-speed it might not meet your 4-speed criteria. I'm unaware of any vehicle made today with a 4-speed manual, but there are several with manuals with more gears.

Millennial here. I drive a Nissan sedan with a 5 speed manual gearbox. Every import manufacturer offers manual as a base transmission. Few dealers keep them on inventory.

Don’t see the big deal and nobody is impressed by it. It is 2021 and people are more impressed by automation like self driving cars and vehicle touch screens, than manual labor.

Geezers never miss a chance to announce how they are old and out of touch with the modern world.

Hey Millennial - it's often been said, "Their generation just has too much." That's why nothing is impressive to your generation, and nothing really lasts built by it ....it's been pretty easy all your life with things we only saw in science fiction movies when we were young. And your generation will be on watch while the world burns because the Boomers were so busy giving you all that comfort, ease, and entertainment - and not making you think more deeply about the real gears that make the world turn.

Very few engineers in your generation....too many social media influencer soy boys.

Today's cars are significantly more reliable than those of the past, and they are much safer as well.

Being able to understand how every machine works is pointless for most. If it is enjoyable to learn, then go for it.

As far as the generational rage being expressed, generalizations make the writer seem facile to say the least.

7am--

Have you lost your mind? Millenials are the ones who are going to work the rest of their lives cleaning up the enormous mess left behind by the spoiled and entitled Boomers.

What you basically said is true for the Boomers' parents--they are the ones who fought in WW2 to give Boomers all the comforts they threw away, they were the last good generation. WW2, Korea, sending men to the moon, etc.

We can thank boomers for:

-Spending their youth in the 60s, 70s, 80s living unhealthy party lifestyles engaging in smoking, unhealthy food, unprotected sex and now are a huge healthcare cost to our system that we have to pay for

-Being fiscally irresponsible and putting this country trillions of dollars in debt

-2008 crash and ruining the economy

-Criticizing technology even though they use it


I can go on and on. But it sounds like you need a reality check about who caused the problems and who is fixing them.

Trollfest '09

Trollfest '07 was such a success that Jackson Jambalaya will once again host Trollfest '09. Catch this great event which will leave NE Jackson & Fondren in flames. Othor Cain and his band, The Black Power Structure headline the night while Sonjay Poontang returns for an encore performance. Former Frank Melton bodyguard Marcus Wright makes his premier appearance at Trollfest singing "I'm a Sweet Transvestite" from "The Rocky Horror Picture Show." Kamikaze will sing his new hit, “How I sold out to da Man.” Robbie Bell again performs: “Mamas, don't let your babies grow up to be Bells” and “Any friend of Ed Peters is a friend of mine”. After the show, Ms. Bell will autograph copies of her mug shot photos. In a salute to “Dancing with the Stars”, Ms. Bell and Hinds County District Attorney Robert Smith will dance the Wango Tango.

Wrestling returns, except this time it will be a Battle Royal with Othor Cain, Ben Allen, Kim Wade, Haley Fisackerly, Alan Lange, and “Big Cat” Donna Ladd all in the ring at the same time. The Battle Royal will be in a steel cage, no time limit, no referee, and the losers must leave town. Marshand Crisler will be the honorary referee (as it gives him a title without actually having to do anything).


Meet KIM Waaaaaade at the Entergy Tent. For five pesos, Kim will sell you a chance to win a deed to a crack house on Ridgeway Street stuffed in the Howard Industries pinata. Don't worry if the pinata is beaten to shreds, as Mr. Wade has Jose, Emmanuel, and Carlos, all illegal immigrants, available as replacements for the it. Upon leaving the Entergy tent, fig leaves will be available in case Entergy literally takes everything you have as part of its Trollfest ticket price adjustment charge.

Donna Ladd of The Jackson Free Press will give several classes on learning how to write. Smearing, writing without factchecking, and reporting only one side of a story will be covered. A donation to pay their taxes will be accepted and she will be signing copies of their former federal tax liens. Ms. Ladd will give a dramatic reading of her two award-winning essays (They received The Jackson Free Press "Best Of" awards.) "Why everything is always about me" and "Why I cover murders better than anyone else in Jackson".

In the spirit of helping those who are less fortunate, Trollfest '09 adopts a cause for which a portion of the proceeds and donations will be donated: Keeping Frank Melton in his home. The “Keep Frank Melton From Being Homeless” booth will sell chances for five dollars to pin the tail on the jackass. John Reeves has graciously volunteered to be the jackass for this honorable excursion into saving Frank's ass. What's an ass between two friends after all? If Mr. Reeves is unable to um, perform, Speaker Billy McCoy has also volunteered as when the word “jackass” was mentioned he immediately ran as fast as he could to sign up.


In order to help clean up the legal profession, Adam Kilgore of the Mississippi Bar will be giving away free, round-trip plane tickets to the North Pole where they keep their bar complaint forms (which are NOT available online). If you don't want to go to the North Pole, you can enjoy Brant Brantley's (of the Mississippi Commission on Judicial Performance) free guided tours of the quicksand field over by High Street where all complaints against judges disappear. If for some reason you are unable to control yourself, never fear; Judge Houston Patton will operate his jail where no lawyers are needed or allowed as you just sit there for minutes... hours.... months...years until he decides he is tired of you sitting in his jail. Do not think Judge Patton is a bad judge however as he plans to serve free Mad Dog 20/20 to all inmates.

Trollfest '09 is a pet-friendly event as well. Feel free to bring your dog with you and do not worry if your pet gets hungry, as employees of the Jackson Zoo will be on hand to provide some of their animals as food when it gets to be feeding time for your little loved one.

Relax at the Fox News Tent. Since there are only three blonde reporters in Jackson (being blonde is a requirement for working at Fox News), Megan and Kathryn from WAPT and Wendy from WLBT will be on loan to Fox. To gain admittance to the VIP section, bring either your Republican Party ID card or a Rebel Flag. Bringing both and a torn-up Obama yard sign will entitle you to free drinks served by Megan, Wendy, and Kathryn. Get your tickets now. Since this is an event for trolls, no ID is required. Just bring the hate. Bring the family, Trollfest '09 is for EVERYONE!!!

This is definitely a Beaver production.

Dr. Heddy Matthias and Lori Gregory will face off in the undercard dueling with dangling participles and other um, devices. Robbie Bell will perform Her two latest songs: My Best Friends are in the Media and Mama's, Don't Let Your Babies Grow up to be George Bell. Sid Salter of The Clarion-Ledger will host "Pin the Tail on the Trial Lawyer", sponsored by State Farm.

There will be a hugging booth where in exchange for your young son, Frank Melton will give you a loooong hug. Trollfest will have a dunking booth where Muhammed the terrorist will curse you to Allah as you try to hit a target that will drop him into a vat of pig grease. However, in the true spirit of Separate But Equal, Don Imus and someone from NE Jackson will also sit in the dunking booth for an equal amount of time. Tom Head will give a reading for two hours on why he can't figure out who the hell he is. Cliff Cargill will give lessons with his .80 caliber desert eagle, using Frank Melton photos as targets. Tackleberry will be on hand for an autograph session. KIM Waaaaaade will be passing out free titles and deeds to crackhouses formerly owned by The Wood Street Players.
