Flat Asked Someone To Redraw It With V1 So I Did

I've recently been seeing this article making rounds around this website and particularly people misusing this very cool advancement to imply that modern nuclear reactors are "unsafe" or "dangerous", which is partially due to the just blatantly bad journalism on display here.

The accomplishment of this new reactor is definitely exceptionally impressive but I think that news websites (Even ones specializing in science) have been mischaracterizing the reactor as "meltdown-proof" which is just - wrong? and implies that current reactors are just begging to meltdown.

The cool thing about this new reactor is that its passively cooled, but that doesn't mean its INVULNERABLE to nuclear meltdowns, for example the Chernobyl meltdown happened completely independently of whether it was cooled passively or not.

In fact, passive cooling would only pose an advantage in situations where ALL pumps and backup pumps break and the core doesn't get coolant pumped to it. That's happened exactly once: in Fukushima and only after a literal tsunami hit it, and there's no reason to think that the passive Helium coolant in this new reactor wouldn't also just break. Fukushima happened because of corruption in regulation, preventing suitable defenses against this exact thing from getting built, not because of unsafe reactor design.

There's also some articles like this one which talk about the new reactor being "self-regulating" which is true, but misses the point that the vast majority of nuclear reactors in service today are also stable in the exact same way. Negative feedback loops are a HUGE part of reactor design, the most popular reactor design today is the Pressurised Water Reactor (PWR) which is incredibly stable - PWRs just truly hate increasing (or decreasing) energy output.

Most nuclear reactors today are already incredibly safe, even if you had complete control over a nuclear reactor it would be effectively impossible to cause a meltdown on purpose - both the physics of the system and the thousands of automated components would beat the ever loving shit out of any hope of trying to do so.

Articles like these just turn this impressive achievements into a kind of fearmongering over the "dangerous" nuclear reactors currently being used. The fact is that nuclear reactors are incredibly safe, PWRs are an incredible feat of engineering genius and its a genuine shame that the general public isn't aware of how much care goes into their design and safety, let alone how useful and essential they are in our electrical systems.

Modern nuclear reactors are clean, they are safe, and they are vital to a healthy energy grid in the post-fossil-fuel future.

A really good read I highly recommend is Colin Tucker's How To Drive A Nuclear Reactor. He's very clear and very frank with the workings and reality of nuclear power today.

"Do you ever dream of land?" The whale asks the tuna.

"No." Says the tuna, "Do you?"

"I have never seen it." Says the whale, "but deep in my body, I remember it."

"Why do you care," says the tuna, "if you will never see it."

"There are bones in my body built to walk through the forests and the mountains." Says the whale.

"They will disappear." Says the tuna, "one day, your body will forget the forests and the mountains."

"Maybe I don't want to forget," Says the whale, "The forests were once my home."

"I have seen the forests." Whispers the salmon, almost to itself.

"Tell me what you have seen," says the whale.

"The forests spawned me." Says the salmon. "They sent me to the ocean to grow. When I am fat with the bounty of the ocean, I will bring it home."

"Why would the forests seek the bounty of the oceans?" Asks the whale. "They have bounty of their own."

"You forget," says the salmon, "That the oceans were once their home."

Our Animal Care team recently completed annual exams on all seven leopard sharks in our Kelp Forest exhibit. From aquarists to veterinarians and volunteers, it takes a small community of shark afishionados to get this important job done!

Each shark was brought up individually by the dive team, anesthetized, and given a full workup. Vet services drew blood, inspected gills for parasites, checked eyes, and examined the elasmobranchs via ultrasound. Meanwhile, aquarists recorded measurements as the sharks woke up.

These annual checkups are critical to the ongoing care of these amazing animals—and it wouldn’t be possible without the collaborative work of our dedicated Aquarium community! 💙

📸 Thanks to staffers Mary and Tiffany for the fintastic photos!

not even JRR Tolkien, who famously developed the concept of the Secondary World and firmly believed that no trace of the Real World should be evoked in the fictional world, was able to remove potatoes from his literature. this is a man who developed whole languages and mythologies for his literary world, who justified its existence in English as a translation* simply because he was so miffed he couldn't get away with making the story fully alien to the real world. and not even he, in extremis, was so cruel as to deny his characters the heavenly potato. could not even conceive a universe devoid of the potato. such is its impact. everyone please take a moment to say thank you to South Americans for developing and cultivating one of earth's finest vegetables. the potato IS all that. literally world-changing food. bless.

[image id: a four-page comic. it is titled “do not stand at my grave and weep” after the poem by mary elizabeth frye. the first page shows paleontologists digging up fossils at a dig. it reads, “do not stand at my grave and weep. i am not there. i do not sleep.” page two features several prehistoric creatures living in the wild. not featured but notable, each have modern descendants: horses, cetaceans, horsetail plants, and crocodilians. it reads, “i am a thousand winds that blow. i am the diamond glints on snow. i am the sunlight on ripened grain. i am the gentle autumn rain.” the third page shows archaeopteryx in the treetops and the skies, then a modern museum-goer reading the placard on a fossil display. it reads, “when you awaken in the morning’s hush, i am the swift uplifting rush, of quiet birds in circled flight. i am the soft stars that shine at night. do not stand at my grave and cry.” the fourth page shows a chicken in a field. it reads, “i am not there. i did not die” / end id]

theres a popular brand in canada called no name brand and it manufactures everything you can imagine in a grocery store and it kind of makes me feel like im in a world no one bothered to do much world building for
