You write e^iπ and only the i ends up in the exponent. If you've ever written LaTeX, you've done this. In Corca you select iπ, right-click, and move it to the exponent.

That being said, we linked variables and words! Right-click a word to link it to a variable. Hover over E, and “energy” lights up in the text. And the other way around.

Writing math on a computer is full of small stops. Three of them are gone this summer: 1. You almost never need the whole derivation. You need one step out of forty, fold the rest

It wasn’t intentional at first, but most of our recent releases ended up solving the same kind of problem. Fewer tabs, fewer copy-pastes, fewer places where your train of thought gets interrupted. Here’s what changed ⬇️

You are using the same variables over and over. It’s nice when the document remembers them.

Corca raised a $7.8M round led by NEA, with NVenture, Daft Capital, and others! We're on track to democratize math for everyone. You don't need to be "good at math" to start. We started with natural math editing, and now AI explains and helps you along the way. Now, back to work!

Most math-heavy work is trying things, getting stuck, changing the model, asking questions, realizing you were solving the wrong problem. It’s also notes, calculations, simulations, graphs, AI conversations, and half-finished ideas. We think those things belong in the same place.

You can just type matrices in Corca directly from the keyboard. Shift+Enter adds rows. Shift+Space adds columns.

Type “integral,” get ∫(x)d(x). That’s basically it.No backslashes or commands. You just type, and it turns into notation. That's the entire learning curve.

Hints are taking care of the mechanical math — evaluating sums and products, factoring and expanding expressions, working with matrices, computing statistics, and using variables defined earlier in the document.

We stopped writing text on paper years ago. But when it comes to math, we still use it. Not out of love for paper, just because typing math is slow and painful. Corca is as fast as paper, but can also CALCULATE.

We haven’t posted here in a while, so let’s unpack what we’ve been working on over the past few months, one by one. Automatic units. Add units to your variables once, and they carry through every calculation automatically. Set v = 10 m/s and t = 2 s, and distance comes out in meters.

NASA isn't why the US doesn't have universal healthcare, or a social safety net. The US doesn't have those things because politicians with the power to provide them choose specifically not to (with varying levels of support from voters). Enthusiasm for human spaceflight doesn't drive that choice.

Not sure if I ever shared the scale model Transit van on here. So I’ll do a bit. It’s basically very loosely based on the types of knackered vans me and mates had and used in the 80s and 90s to cart band gear about in. This is 1/24th scale.
The front bench seat of a yellow van complete with cans of lager.The underside complete with rust, holes, oil leaks and a flat tyre.

Under the hood, it is the actual SymPy running locally via wasm. Currently, we support only a small fraction of its capabilities, and we are working on expanding that coverage.

Whoa! Just came across #JWST Helix Nebula image! Left is my backyard image of the Helix Nebula. Right, JWST is looking at the same nebula. Little white box in my image is about same size/location as the 2nd image. (assuming) JWST: 📸 PI: Garcia Marin, Macarena / NASA/ESA/CSA/STScI/j. Roger 🔭
a central, large ring-like nebula. The inner part of the ring is a blue-green colour and is diffuse, whilst the outer ring region is reddish in hue, much more defined and clumpy. A central small white star, the white dwarf, emits powerful UV radiation which excites the different elements producing different colours. Surrounding the nebula are many stars. Images on left are higher resolution. A small white box is annotated towards the top of the nebula.clumpy, purple colours nodules of gas in space. In the background are a few galaxies that are distant, small and peek through the clumpy material. The material is the inner part of the Helix Nebula gas and dust ring. The nodules are long and tubular shaped, mostly oriented in the same direciton as this material as been stripped by the central star that is out of view of the image.

Text is a string. Math isn’t. It grows in every direction into multi-line structures. That’s why people still do math on paper. We’re bringing that experience to computers. Corca is WYSIWYG math editor, and it's fast!

This is a solar eclipse on Saturn. Titan transits in front of Saturn and casts a shadow. Made this timelapse yesterday, one frame every 3 minutes. Couldn’t capture the whole event because of clouds and those stupid trees.
