All I need are PO-TA-TOES! Boil em’, mash em’, stick em’ in a stew!

westgot

edible doesn’t mean it tastes good or is easy to cultivate.

Sayrenotso

Great, now I’m trying to see if I can name off 30 plants.

theinsanityoffence

I like the fact that the Wikipedia-page is called “Neglected and underutilized crop”, as if it’s shaming me for my undiversified plant intake.

oatato

Most people on earth have to rely on affordable basics to survive, such as rice, corn, wheat and potatoes.
I underatand the point you’re making here. But it’s not that simple. It doesn’t make sense (w.r.t. nutrition) forcing more people to eat useless superfoods.

TIL about the heroism of Teddy Sheean, of the Australian navy. During WW2, his ship was torpedoed, and Japanese planes shot at survivors in the sea. Sheean strapped himself to an antiaircraft gun on the sinking ship and fired at the planes, downing at least one. He was still firing as he drowned.

‘Fight on’ is the Motto of the Submarine named in his honour. HMAS Sheean.

His family has been campaigning for years to have him posthumously awarded the Victoria Cross but it hasn’t happened yet. A couple of kids I was at school with are related to him

There’s a reason they’re referred to as ‘the greatest generation.’ The more you read up on WWII the crazier it gets.

MojitoBlue

So brave

Venusflytrapp

He was still firing *as he drowned*? I don’t understand that claim.

LoreleiOpine

TIL that the dust storm that sets off the events in the film “The Martian” isn’t plausible because the atmosphere on Mars is about 1% as dense as Earth’s and the winds in the strongest Martian storms top out at about 60 miles per hour, unlikely to tip or rip apart major mechanical equipment.

I think Andy Weir has stated that he knows the storms wouldn’t be like that on Mars, but he needed the plot device to get things going. I think he said that was the weakest point of the plot.

moose4130

Plus Sean Bean survives to the end, that movie is full of scientific impossibilities

keith_richards_liver

>Mars’ dust storms aren’t totally innocuous, however. Individual dust particles on Mars are very small and slightly electrostatic, so they stick to the surfaces they contact like Styrofoam packing peanuts.

>The possibility of dust settling on and in machinery is a challenge for engineers designing equipment for Mars.

TIL The Martian isn’t a documentary.

TIL the word “Apple” didn’t always refer to the specific fruit. As late as the 17th century the word was used for all fruits that weren’t berries.

Pomme de terre = apple of earth, French word for potato

GenXCub

Bonus TIL: **corn** was the same thing for vegetables.

ElectronGuru

The irony being that apples are berries.

ElfMage83

This means the forbidden fruit in the Bible isn’t an apple as European drawings depict.

ChiggaOG

Does this imply that ‘Eat an apple a day…’ refers simply to fruit? Any idea when that particular saying got popular?

LeftBrainedGirl

TIL about Patton’s Prayer. During The Battle of the Bulge, clear weather was desperately needed to advance. He asked a chaplain to write him a suitable prayer. The chaplain complied, and the ensuing prayer was handed out to the troops. The weather cleared, and Patton gave the chaplain a Bronze Star.

This is the prayer:

> Almighty and most merciful Father, we humbly beseech Thee, of Thy great goodness, to restrain these immoderate rains with which we have had to contend. Grant us fair weather for Battle. Graciously hearken to us as soldiers who call upon Thee that, armed with Thy power, we may advance from victory to victory and crush the oppression and wickedness of our enemies, and establish Thy justice among men and nations. Amen.

Jontolo

I knew this fact but I love it so much. The reason being the battle of the bulge was so rough as far as weather goes as it got in ww2. If it had been any worse we wouldn’t have prevailed. There were americans fighting barefoot in that battle ffs. As a veteran of afghanistan it almost makes me not consider myself a veteran. I’ve been on the receiving end of fire and fired at enemies. The men in the battle of the bulge are absolute fucking troopers. I dont think men of that caliber still walk the earth. At least as much as they do now per capita. I’ve been through some shit. Battle of the bulge nibbas earned the eternal triple og status. For eternity.

And then he slapped him for good measure.

So what would he have done to the chaplain if the weather sucked?

TIL of the Machine Identification Code. A series of secret dots that certain printers leave on every piece of paper they print, giving clues to the originator and identification of the device that printed it. It was developed in the 1980s by Canon and Xerox but wasn’t discovered until 2004.

No. Several of us discovered it in the 80’s and made a huge stink about it. We were called conspiracy theorists and dismissed. Some of us went to enough trouble to prove it, comparing the yellow dots under microscopes/magnification and UV from multiple printers and multiple pages. We proved it. They lied and said no.

justscottaustin

There’s a black market for stolen printers in many countries (Africa is particularly bad) to get around the tracking code issue. I mean commercial printers like I use at work (as a printing business). We’re talking about skilled technicians disassembling a multi-ton device that needs a crane and forklift to remove. Like in a hollywood heist movie, but for printing certificates. It’s a waste of time copying banknotes, ID papers and vocational training and qualification certificates are where the money is.

Been aware of this tech since the mid 90s. Yellow dot patterns because that’s the human eye is least sensitive to.

fudspong

And that’s why you need cyan even if you only print a black and white doc.

augustomen

That’s why you need to dump your printer after printing the ransom note

There is no way my printer does this. Despite not using it, it is always out of colored ink.

TIL Julia Louis-Dreyfus once parked in Tom Arnold’s parking spot on the CBS lot. He left a note on her windshield that read “How stupid are you? Move your f–king car, you asshole!” She later found “a Polaroid of someone’s buttocks left on her windshield and the word ‘cunt’ written in soap.”

It’s not often Tom Arnold comes up, so this seems like the opportunity to say he used to smoke meth with my disowned grandmother back in the 90s. His sister was a meth kingpin (queenpin?) in Iowa back then. Not the best people.

Orion2350

Whoever wrote “cunt” and left the butt pic probably thought it was Tom Arnold’s car. It’s just a coincidence that she was parked there.

zombieofMortSahl

Tom Arnold is a fucking piece of shit. Also .. Julia is 5000 times a bigger star than him.

Tom Arnold’s a piece of shit, he offered Julian $10,000 to bang Lucy and Ricky got pissed.

TIL forcing left-handed children to write with their right hands is not in any way innocuous or helpful- it is actually harmful to their developing brains and can result in dyslexia, stuttering and other learning or speech disorders.

My dad was naturally left-handed, and grew up in an era where it was seen as a ‘corrective disfigurement’. He was told to use his right hand to write and would be caned if he switched to his left. He was functionally ambidextrous for the rest of his life, but his handwriting and spelling were atrocious.

Vyzantinist

Ha, I learned to read upside down first, from being read to, and had my “devil’s hand” taped to my back when learning to write.

Old fart.

mad-n-fla

My teacher tried that to me and then she met my mom. Didn’t end well.

slothycorn

My teacher “corrected” me, I’m fairly ambidextrous now, but my handwriting is crap with either hand.

wrightk1979

Hmm I don’t get why people would be so interested in changing a thing like that. My son is left handed while everyone else is right…we have had zero problems with him being left handed.
