There is supposed to be Word Block Descriptions for the block language under Help & Support in the Settings, but that seems to be missing at the moment (in v10.0.2). Hopefully it will be fixed in the next update.
For Python, there is a Knowledge Base on the side of the screen. Click the book icon to show or hide it.
IR Transmitter Tower exist in both USB version as well as Serial cable version.
Page 7 of instructions for one of the sets (3804) that was using USB version has following explanation:
The IR Tower establishes a wireless link between your computer and the
RCX. With the IR Tower, programs can be downloaded from computer to
RCX. These programs ...
Why they exist: to transmit programs from your computer to the Mindstorms smart brick (which is really another, probably smaller, computer). This was before USB ubiquity, and it also prevented children from plugging and unplugging a cable at the back of their computer, which is a dangerous move, even for adults.
Brickset identifies JØRN THOMSEN as the designer of the 31313 set:
Although I'm also inclined to believe that probably a group of people came up with the various initial robots.
I think that actually the five main robots were made by a group of people.
On this page, it tells who designed the fan robots, but it doesn't say so for the 5 main robots, which include EV3RSTORM.
To quote from this site:
Like the early robot turtles, these programmable Lego constructions were still tethered to a computer with wires. So Seymour Papert ...
Printing text in pybricks-micropython on ev3dev has known performance issues, so we don't recommend doing that in a loop. The trade off is that, unlike ev3-g, you can also print in other languages that don't use Latin scripts like Chinese and Russian. Most other things should run much faster.
The web-based EV3 manager will not let you upload an 'E' (education) firmware in a Home edition brick. For some reason the latest education version is 1.10E while the home version is stuck to 1.09H.
But you can use the EV3 software to point to a specific file to upload. Version 1.10E is available here: https://education.lego.com/en-gb/product-resources/...
The "App" page does seem to be hard to find at the moment. I found it by clicking on this little icon on the MINDSTORMS "About" page.
The app is distributed through various app stores:
Microsoft Store (Windows)
Apple App Store (macOS/iOS)
Google Play (Android/Cromebook)
Amazon App Store (Kindle Fire)
There isn't currently any option ...
