What if Monty only opens a door when he knows you've chosen the prize door? Extension: what if Monty tosses a coin to decide whether to open a door, conditioned on you having chose…

What this article misses out is that the metrics will be present and used whether they are articulated or not. By making them explicit they can be improved, validated, debated, and…

This sounds very much like OCD. One of the nastier traits of OCD that I experienced with a partner was the tendency for the OCD to hide itself, by convincing the sufferer that they…

Black is in check from the white rook. Moving the black night doesn't escape the check, so isn't a legal move.

The article doesn't actually specify that 78% guessed correctly or incorrectly, just that 78% guessed without ever entering an invalid sequence.

Almost certainly because it increases engagement. By optimizing purely on metrics, psychologically undesirable effects creep in (guilt, in this case). c.f. online gaming apps and t…

I think it's important to acknowledge the distinction between chatting to a bot and not being convinced that it's a human, and having two conversations simultaneously, one of which…

Rather than starting with an assumption on avg revenue per user, start with the valuation, figure out what that would imply about revenue/revenue growth, and you'll probably learn …

Aside from medication, for OCD in particular there are therapeutic options that can be (life-changingly) effective. The OCD centre [ http://www.ocdcentre.com/about-us ] is one such…

Pretty sure it was Antigrav by Nicholas Fisk. It was a cool story - if you were a kid. I never did find any red pebbles though.

The scope of Elite was so impressive - and the novella that came with it added so much to how big the universe felt. What sticks in my mind is that the only way to make any real mo…

The retina display on the 13" MBP actually results in less application real estate at native resolution than the 1440x900 on the MBA. It's also half a pound heavier, more expensive…

Sorry, but no. The conditions of your entry to the US will state pretty clearly whether or not you can work. If you're on a tourist visa, you can't work, if you're on a business vi…

I remember reading several years ago that in the UK lottery 10000 people every week play 123456. And thus would be very disappointed at their £500 payout.

At an atomic level, water plays critical roles in very small quantities and understanding these role requires detailed simulations. See this recent paper [1] for an example of how …

Round the corner from my house in Richmond Park (London), there is a large population of deer who carry the bacterium that causes Lyme disease (and apparently several other excitin…

Some other contributing factors: cultural attitudes to failure, and as a consequence cultural attitudes toward entrepreneurs, heterogeneous audiences (the USA has ~300M people spea…

GPA - absolutely. If it's not there, the assumption will be that the reason it isn't there is because it's bad (especially as a new grad). Like when you look at a 2nd hand car list…

Can't go too far wrong with a solid brand like Lowe Alpine, or Berghaus. Pick one up on sale if you can, backpack technology moves pretty slowly so you hardly lose anything from bu…
