With the best illusions, you can know how they're done and yet your mind's still immediately flummoxed.
This is my favourite. Those table legs? Impossible - but absolutely real. (This is a *photo*.)
An appreciation 🧵for the oldest trick in the book:
1/
Here is Professor Brian Cox CBE OBE (far right of pic) in his former p/t job (1986-1992).
I post this to illustrate that scientists still have *all sorts* of backgrounds, including in the Arts...
(And maybe also because this photo is amazing. Which it certainly is.)

In the case of Adelbert Ames Jr. (born 1880), he started by studying & practicing law - then chucked it all in to try his hand at painting.
Along the way, he developed a passion for light & colour & how the human mind processes them - and ended up a professor of research.
3/
Take Augusta Ada King, Countess of Lovelace, born 1815, who has a solid claim to being the world's first computer programmer.
She was a visionary, she hobnobbed with the greatest minds of her age (being one herself) - & she crammed an astonishing amount into her 36 years.

But no. I typed "scientist" into Google and the very first image result was labelled "Mad Scientist Pictures", featuring an old white bloke with barmy hair. The stereotype is hard to kill, even now.
Sigh.
(The other images were more encouraging, though.)
5/
Returning to Ames: outside of physiological optics, his most famous work is a type of room where impossible things happen.
You've seen it used dozens, maybe hundreds of times.
It works on you every time - & it always will.

Here's illusionist Zach King showing it in action at the start of this video:
(The rest of the video is a mix of practical & digital effects - but the Ames room is 100% practical. No expensive CGI needed.)

I won't go too far into the details. If you're interested, there's more in the newsletter I just wrote on all this:
I may have written about the least interesting person here. Here's a profile of Blanche Ames, sister of Adelbert, which starts with this arresting scene:
So I got curious. What else don't I know about these amazing things?
1/
Firstly: they're not just green.
Different heights of our atmosphere = different gases, & when charged particles from the sun excite gases at different altitudes, you get different colours.
*Wildly* different. Blue, pink, purple, yellow and (rarely) red.
I had no idea.
2/
Secondly: here's a weird thing discovered during an aurora above British Columbia:
"The temperature 300km above Earth’s surface jumped by 3000°C and the data revealed a 25 km-wide ribbon of gas flowing westwards..."
It's common for writers under terrifying deadline pressure to rely a bit too much on Wikipedia? Ahem. Easily done. It can't be TOO far wrong?
But a few months ago, researching a newsletter, I learned just how disastrous this can be.
An alarming 🧵 with good, hard LOLs:
1/
I'm old enough to remember t'days before t'Internet (black & white, everyone walked really fast, piano music etc) so I can emphatically say I love Wikipedia.
An encyclopedia edited by nearly 200,000 people - and it's *readable*? (And democratic?)
I'm a fan.
But...

OK.
Have you heard of the Bicholim conflict?
It's an obscure 17th-Century war that raged between the Portuguese rulers of Goa, western India, and the neighbouring Maratha Empire.
Don't look for it on Wikipedia, though. It's not there.
...and all the examples I found are delightful, ludicrous and worrying! (It's amazing how completely it hijacks our mind.)
I dare you to unsee the following examples.
1/
In 1994, Diana Duyser of Florida spotted...something in her grilled cheese sandwich (the "Holy Toast").
She immediately did what any of us would do: packed it in cotton wool & waited for eBay to be invented, so she could auction it to online casino Golden Palace for $28,000.
2/
If you’re wondering how it didn’t evolve into an entirely new lifeform during that 10-year wait, here’s some science about how a grilled cheese sandwich can last a decade without going moldy, via @Slate:
Seeing the Northern Lights is one thing - but have you ever seen a *city* up there?
Yes, like that scene in ep. 1 of 'His Dark Materials'.
Because here's the weird thing: they exist. You can indeed see cities in the sky. There's actual science on this.
Stay with me. 🧵(1/)
That’s what Jesuit priest Father Domenico Giardina saw on August 14, 1643. Looking across the Strait of Messina (Sicily), he beheld “a city all floating in the air...so splendid, so adorned with magnificent buildings, all of which was found on a base of a luminous crystal.”
2/
If his record is to be believed - as he watched, the city shimmered and became a garden.
And then a forest.
And finally a landscape of vast armies, locked in combat over the ruins of buildings...
Last week, I got seriously obsessed with what, at first glance, looks like a really daft question:
What does the Internet actually *look* like?
All the ways to answer this are fascinating and full of surprises. Here are some in a thread:
1/
Here is the simplest, most straightforward and wrongest answer.
It looks like the box in the corner of your room that you sit in front of every day, "enjoying" its contents.
Devoid of context, that's what my senses tell me. But obviously this is absurd. Let's move on.
2/
If "the Internet" is the signal, all that data flying around, then in a sense it looks like this.
99%+ all international data races along sea floors at around 16 mill. times the force of a home Internet connection, through cables roughly the width of a can of Coke.
