You can graft a tomato plant and a potato plant together so the one plant can produce potatoes underground and tomatoes above ground because they are from the same family.

[–] Trex202@lemmy.world 13 points 6 days ago

Yes it's possible, but the tomatoes and the potatoes fight for resources and make subpar produce

That sharks as a species, are older than trees, flowers... and older than the rings of Saturn.

"Get off my sea-lawn"

-- Sharks probably

[–] hakase@lemmy.zip 24 points 6 days ago (1 children)

They're also older than Polaris. Not just older than since Polaris has been our North Star, but older than the star itself.

God damn the ocean is terrifying.

If you live in America and live to the age of 79 there is a possibility that you have walked by or interacted with 36 active serial killers.

I'll probably butcher this fact, but 20/20 vision does not mean you have perfect vision. It means you have average / normal vision.

I've always had 20/20 (or perhaps better) vision. But now that I'm on the downhill side of ancient, I'm noticing that my vision is blurry. Especially while watching TV, reading, etc.

Yet, at both my primary care provider and at the optometrist, I'm able to accurately see all the letters on the vision charts and based on that I have 20/20 vision.

The optometrist (or maybe it was an assistant) explained that it's pretty common and that 20/20 is just average vision. It doesn't mean your vision isn't blurry and it doesn't mean you won't benefit from glasses.

The more you know!

Recently had lens replacement surgery (AMA?) which gave me 20/15 far sight vision. Seeing things up close is difficult (need reading glasses) but making out details from far away objects is unreal. It's like having HD vision.

Anywho, 20/20 simply means that you can make out details at 20 feet that the average person can make out at 20 feet. In my case, I can make out details at 20 feet that most people can only make out at 15 feet.

If you have 20/40 vision, it means that what most people can make out at 40 ft, you can only make it out of it were 20 feet away.

Now you know how that works.

[–] InvalidName2@lemmy.zip 2 points 5 days ago (1 children)

What was the recovery from that surgery like? Any pain / discomfort / concerns?

I am considering getting lens replacement for my dog if I can come up with the money, but financial concerns aside, my other biggest concern is how stressful / painful / risky that kind of procedure might be for her.

[–] Skanky@lemmy.world 4 points 5 days ago

Well, not being a dog, I can't really say for certain, but I'm sure your puppy will be fine. For me, there was little to no pain at all, even during recovery. Only mild discomfort, and I mean very mild. It's outpatient surgery and the actual procedure only takes a few minutes (for one eye). It was really no big deal at all

Yeah, my glasses actually correct past 20/20, but my contacts only correct to 20/20. So everything is more blurry when I wear my contacts.

[–] garbagebagel@lemmy.world 2 points 5 days ago

I learned this the hard way earlier this year when I got lasik. I used to be able to read the clock from across the room in my house with my contacts, but now that I have 20/20 without contacts, I can no longer make it out. So I guess the contacts were giving me a slightly higher than average vision.

Interesting! Is your vision still good other than nearsightedness? I wonder if there are other methods of labeling vision that could more accurately describe that.

You can harvest asparagus twice a day.

[–] IWW4@lemmy.zip 3 points 5 days ago (1 children)

wow. Do they grow that fast or is there some mechanism that one triggers with the plant?

[–] YiddishMcSquidish@lemmy.today 2 points 5 days ago

They take a few years to get established, but they just grow that fast.

Liu Cixin, the author of the trilogy, Remembrance of Earth's Past (aka Three-Body Problem,) had written 4 novels and over 20 short fiction works, before they had their first major international hit.

It's a solid reminder for me to write my stories. 'Get them out of the way,' so I can work on the next big thing and get it out there.

[–] theherk@lemmy.world 12 points 6 days ago (1 children)

There is an anecdote that I can’t currently find, nor am I certain I have the author and story right.

But there was a person who picked up Fifty Shades of Grey while his wife was reading it and claimed he could write better in spite of not being an author; I think they were a programmer. Anyway she challenged hisband Dennis E. Taylor who then wrote the Bobiverse.

So… maybe you just need that first one to really get going.

[–] halcyoncmdr@lemmy.world 9 points 6 days ago

Also a reminder that Fifty Shades of Grey started out as a Twilight fanfic titled "Master of the Universe". Which honestly adds a lot of context to the characters, you can basically just substitute names and it works.

[–] shalafi@lemmy.world 5 points 6 days ago

Vonnegut didn't get famous until Slaughterhouse-Five (1969). He had already written a load of what are now classics but still had to have a day job.

Player Piano (1952) The Sirens of Titan (1959) Cat's Cradle (1960)
Mother Night (1961) God Bless You, Mr. Rosewater (1965)

I'm sure there were also loads of short stories in that time frame.

And for anyone who hasn't read Vonnegut, I think it's important that you try.

Similarly Scott Cawthon, the creator of Five Nights at Freddy's, created 79 games before FNAF.

The water in rain falling in the west of Lake Superior will take 200 years to reach the Atlantic.

[–] TehBamski@lemmy.world 4 points 6 days ago (1 children)

What? How the heck does that make any sense? Also, how would you even track that with high accuracy?

Estimations are made from the lakes depths, sizes and flow rates. Superior is fed by 200+ sources, but less so for the downflow lakes. Several are only fed by the uphill lake. This gives better accuracy when making estimates on how long it would take to replace all the water contained or travel time of the water itself.

Here’s another: According to fossil evidence, the Grest Lakes used to flow towards the Pacific, but an object, thought to be a comet, struck Lake Ontario (Charity Shoals) and changed the flow to the Atlantic.

Okay, one more: The Great Lakes are tilting over time. The Lawrentian ice sheet depressed the crust of the earth so much by its weight that it is still rebounding. I believe it is Lake Huron that they can see the tilt level changing about a tenth of an inch a year to the south.

The Great Lakes are truly a marvel of nature.

Not a new one, but I've learned more recently:

Water does not last forever, is not all dinosaur pee. Natural processes create and destroy it, nonstop, since forever.

Got any plants nearby? Those fuckers are busily cracking water into glucose and oxygen so that you can breathe and eat. Have you said thank you once?!

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Take a shot of baking soda for your heartburn, oh boy will you create water!

NaHCO3 + 2HCl → NaCl + H2O + CO2

CAVEAT: The gas comes up your pipes, the water goes down your pipes. Violently. Probably a gravity thing. Not for the faint of heart, but hey, no heartburn!

[–] corsicanguppy@lemmy.ca 2 points 5 days ago

the water goes down your pipes. Violently.

That's what salt water does. That's how people die when they are in a life-raft and drink seawater: defecating terminally.

So I hear, thankfully only second-hand.

[–] PillowD@lemmy.world 3 points 5 days ago

If you are lost in the wilderness and a plane comes in to look check on you, do not pump your fist in the air. That is the signal you are fine and don't need help. Learned it in a recent Mr. Ballen youtube.

Chard and Beets are the same plant, one just specced into the root bulb part (beets). Also chard came first!

[–] jimr1603@lemmy.world 3 points 6 days ago

I believe the creator of this said the same plant could make fries and ketchup
