You can find out if an operand is true by looking at it. If this does not answer your question you need to provide more context.

Yes but you didn't fix this: ...although that is obviously what you mean if you have derived ## m=\log_2(n−k+1) ##. Anyway you are looking at this the wrong way round: ## m=\log_2(n−k+1) ## is not much help. Instead read the solution and consider how many elements there are in a heap of...

Yes, it is fun. Online gaming interrupted by som real life sporting events at the moment though!

This could be a concern, but the fact that it charges at all over USB C indicates that it will be plenty - it wouldn't be worth implementing PD otherwise.

That would work but I think you would find something like this more versatile: https://a.co/d/04Y7H582 - you could charge your phone too at the same time. You'll also need cables e.g. https://a.co/d/0idWyBHy

Is this an Aspire? I wouldn't go anywhere near it with any kind of soldering equipment, in fact I wouldn't even take the case apart unless I was prepared to hold it together with duct tape for ever after. Those things are built down to a price and are effectively unmaintainable. If you can use...

They do but they don't talk to each other (Windows <-> Android) so a (paid for) 3rd party password manager is most convenient, and will also store credit card details for cross-platform use. I use 1Password.

Yes, but because Sci-Fi Writing and World Building was already a child of Science Fiction and Fantasy Media it has now ended up a grandchild of General Discussion. Are there any other grandchild forums, and if not then why not make Science Fiction and Fantasy Media Sci-Fi Writing and World...

Looking even better now @Greg Bernhardt (in light mode at least, haven't spent much time in dark mode yet) :smile: The forum rearrangement has ended up with some sub-sub-forums e.g. General Discussion > Science Fiction and Fantasy Media > Sci-Fi Writing and World Building: is this intentional?

Has anyone else seen this new game based on first (alien) contact? Playing through the demo I was initially disappointed but by the end of the demo I realised that I was wrong. I haven't got any time for gaming at the moment but I'm looking forward to going deeper.

I'm great thanks, been mostly away for a while with family issues. This seems to have done the trick. I'll just move closer to the screen on the home page :-p

I've looked at a few more of these: red, green, blue, brown, purple are all OK for me, it's just the grey. Maybe it's just me? They are all OK in dark mode.

In the Homework Help forums the two-column layout for Homework Statement and Relevant Equations crowds all the content into half of the screen of a mobile phone. Either stop using the two-column layout altogether or put it in a media query for >= desktop.

I like it. My personal thoughts, I've only looked at light mode for the moment: Thread page The thread display – 16px Inter – is a great choice for main content. 13px is too small for quoted text, why override the default 15px? 12px is too small for the signature – 13px is OK here. The Prism...

This is an old thread and we seem to be overcomplicating the symmetry argument. In order to show that ## t_{up} = t_{down} ## all we need is ## v = u + at ## and conservation of energy. At height ## h ## on the way down the ball is travelling with velocity ## v_h ## and the velocity of rebound...
