Just like regular bikes, it depends on how the bike and car lanes are layed out. If you keep them seperate the bike is unlikely to be hit.

Except wolfram alpha is able to correctly explain step by step solutions. Which was an aid in my education.

Just draw the triangle the other way for DD/MM/YYYY. It makes sense that people want to know the day first, that is the most important part tbh

That would be highly unusual

You can have multiple users on android. Some plugin should be able to do such a thing.

Pretty creative problem solving!

Nice bonus that the hole you needed to drill was sized similarly to the central hole for the bar.

Sometimes making things is not about the most fancy stuff, just making something fit for your purpose can be great too.

Cern has produced quite some interesting systems for software and data management. I am sure the added value of the work is beyond just understanding particles.

Its a mass produced bearing type. Most likely the cheapest option for both devices. Optimizing a bearing for a gerbil wheel seems like the real overengineering in my opinion.

In Dutch: ant football

Some effects started before brexit was official. As institutions and individuals sought to minimize negative impact. I recall reading about european students leaving british universities pre brexit.

My understanding is that in a true vacuum light will not be reflected or bent by particles. However, due to gravity bending space time itself, light will follow the curvature of space. It would depend on the observer if the path if light is straight. If you look at the light passing by, it would not be straight under influence of gravity. If light itself is the observer, it will travel in a straight line :)

In the case of gravitational lensing the observer is looking at light coming in. An outside perspective.
