Drain the oceans and flood the land with this sea level simulator

You’ve surely seen interactive maps showing the effects of the sea level rising, but Sliding Shores makes a game of it: you get a beautifully-rendered globe and a slider to raise or lower the oceans. There’s a load of presets, from “oceans drained” to “drown Everest,” a feat not even Waterworld managed.

Here’s the actual tool: Sliding Shores — Interactive Sea Level Rise Simulator by Richard Franklin.

(It had me at “Boil off 100 feet and we get Doggerland back!” Want to more about why that’s cool? It’s a real-life Atlantis, kinda sorta! Check out this backgrounder.)

This month marked the Hubble telescope’s 200,000 orbit around Earth. That’s a lot of laps!

NASA marks Hubble’s 200,000th orbit around Earth with a stunning image

Hubble has been operating in space for more than 36 years and is still making discoveries. The space agency noted that the telescope has traveled over 5 billion miles around Earth during its lifetime and has made more than 1.7 million total observations. 

Click through to the article and the related NASA links to see an image of (checks notes) galaxy cluster MACS J0417, taken the day Hubble crossed that milestone. Here’s to science!

I’ve always been more of a word person than a math person, but I do enjoy experts who can translate their area of expertise into sharable concepts with roots in what matters for everyday life.

In this (fair warning, very substantive) video, one of the world’s best mathematicians shares some of the “extremely intuitive concepts” that underpin his forthcoming book on, what else? Math!

The world’s greatest mathematician explains 6 essential concepts of math – Big Think

If we didn’t have numbers, we would have to always speak poetically when trying to describe any situation, and it would always be a little bit imprecise, and the next person who’s communicating what you’re saying would get it slightly different. Numbers allow for precision. They are placeholders for concepts like quantity and size and magnitude, into very portable things that you can communicate to other people who may not have directly interacted with the objects you’re describing. And once you try to describe a very complicated scenario with many, many moving parts, you need numbers and everything else that’s born on top of that.

Do I like speaking poetically? I do, but a ten-page description of the state of the world is not terribly useful when it comes to calculating the price of gas.

I think this application of language to science is really cool, and speaks to the layered memories that are built by each successive generation, if only we know where to look.

“We thought that as native oysters are now really rare throughout Europe, is there a way to look where they used to be, using people’s memory and understanding – that can come through place names.”

Here’s a good use for self-driving technology (just on another planet):

The first self-driving vehicle on Mars has proven to be a smashing success

Much like self-driving cars on Earth, Perseverance has sophisticated onboard cameras that image the surrounding terrain, and these images are then processed algorithmically by an onboard computer to calculate the safest route. Terrestrial vehicles have some advantages of course, like clearly defined maps, street signs, lanes, and more. Additionally there are plenty of “road” hazards on Mars, from large boulders to sandy slopes. But at least Perseverance does not have to contend with other traffic and bad drivers.

Here’s how far the little rover has come:

Want to know where Perseverance is now? Here’s the Perseverance Rover Location Map.

Scroll and pan around this map to see the rover’s latest location and traverse path, as it seeks signs of ancient life and collects samples of Mars rock and regolith (broken rock and dust) for potential future return to Earth.

Here’s to Perseverance!

This week marked the 60th anniversary of Star Trek (it was Tuesday, actually, but alas! I was distracted by the whole “return to work” thing). And the show almost didn’t make it at all.

How ‘Star Trek’ almost failed to launch

“The Cage” – a complicated story about alien mind-control – was an ambitious pilot. When Roddenberry presented it to NBC, the programming executives were blown away. But the sales and marketing department wasn’t convinced. Not enough action, they thought. It would be hard to promote. Pass.

“Star Trek,” it seemed, was dead.

Fortunately, there’s more to that story, and the show not only got off the ground but became the entertainment juggernaut it is today.

I wasn’t a Trek fan growing up, in large part, I think, because my parents had made the conscious decision not to have a television. Now that I’m all grown up and have a TV of my own, though, I appreciate the ideals and more behind the sometimes campy but always fun franchise. So inspiring, and not just for everyday fans. 

‘Star Trek’ and NASA have intertwined legacies – the show championed diversity and inspired generations of real space scientists

When it premiered in 1966, no one could have predicted that it would lead to more than a dozen spinoff shows, more than a dozen movies and one of the most enduring fandoms in popular culture.

“Star Trek” is also unusual for its close connections to NASA, both in its storylines and in the real world. Decades of “Star Trek” adventures have ignited a love of spaceflight across generations, inspiring many who now work as space professionals.

Let’s hear it for the real-world powers of fiction. And now, in life and the imagination, go boldly!

It’s a beautiful day here, all blue fall skies and fluffy white clouds, and birds singing in the back yard. What, one might wonder, did the landscape sound like in eons past? Before technology? Even before humans? 

There are still a lot of questions to answer, particularly about dinosaurs and other creatures with soft tissue that has not traveled to us through time, but insects? That, we now have a better handle on.

What Did Jurassic Forests Sound Like? Like This.

Scientists spent over a decade reconstructing the calls of nine species of ancient insects to create the first accurate Jurassic soundscape.

Something to think about if you are a writer building a soundscape for your world. And having spent much of the weekend with mosquitoes buzzing in my ears, I can only say that insects certainly can make an impression!

What Happens When You Put an AI-Powered Banana Casino in a Monkey Reserve?

The team started by building a homebrew AI-powered facial recognition program called CapuchinAI. They then installed it on a computer outfitted with a camera and touchscreen, loaded it in a protective DIY box, and included a dispenser to dole out dried forest banana slices. When CapuchinAI detects a monkey’s face, the touchscreen turns on. If the monkey triggers it, the machine dispenses a tasty banana slice. Simple as that.

I try to share big astronomical events, but I was in the northern woods and missed the lunar eclipse on August 28th. Luck was with me, though. I happened to be awake around midnight and looked out the window to see 93% of the moon missing. What a lovely and unexpected surprise!

In case you’ve been wondering what happened to that stray SpaceX rocket part heading for the moon?  

New photos show site where SpaceX Falcon 9 rocket crashed into moon

And if you, like my friend Elaine Midcoh (great story, recommended!), are interested in the legal status of lunar-based events, this article has some preliminary thoughts.

Despite a lack of momentum toward a new legal framework, there are substantial mechanisms that can be taken now to mitigate harm from cislunar activity.

Best to prepare now, I think, while the regolith is still clear.

“If you believe you can accomplish everything by “cramming” at the eleventh hour, by all means, don’t lift a finger now. But you may think twice about beginning to build your ark once it has already started raining” [rocket parts]. — Max Brooks (with a minor addition)
