Check your user profile.

In the app I use, the user profile shows my own activity, and has a menu for things like "upvoted" and "downvoted".

Your app (Summit) might well do the same. Otherwise check the regular Web interface (no app).

I downloaded the game and its source code, and I have new information for you.

There is an upgrade (this game calls it an "extra") that lets the ball break through that middle column of bricks.

The extra you want looks like a ball with a lightning bolt on each side. Something like:

⚡🪩⚡

It seems to be called METAL or ENERGY BALL.

I don't know this breakout game, but some have bricks that are tough without being unbreakable. Hit the same brick enough times, and it eventually breaks.

In a breakout game that has upgrades, there might be an upgrade that helps you get through.

I dug up the actual paper (Cook, 2004) and it turns out the bicycle was symmetrical... and, in fact, entirely virtual.

It's a plot of a computer simulation, rather than records from a real-world physical experiment.

A bicycle is composed of four rigid bodies: the two wheels, the frame, the front fork (the steering column). Each adjacent pair of parts is connected with a joint that allows rotation along a defined axis, and the wheels are connected to the ground by requiring that their lowest point must have zero height and no horizontal motion (no sliding).

So the simulation has a lot of simplifications from reality, and the picture tells us more about the simulation model than it tells us about the real world. It is a pretty picture, though.

Here's the paper reference:

Cook, M. 2004. It takes two neurons to ride a bicycle.

(I couldn't get it from the Cook's Caltech site, but I found a copy elsewhere.)

At a basic level... yes? I think all those words are important enough in English to be short words. They're important in a way that "theatrical" and "equally" are not as important.

And none of those words are as important in English as "a" or "I".
