I just flew from UK to USA and the UK security (Heathrow) made my 5-year-old daughter go through the body scanner!! Ie, the first metal detector arch beeped for her (I think it was a hair clip she had on) and they said she had no choice but

This will expose you to cutting edge research going on. But I disagree entirely on this approach to learning fundamentals of math and physics. The colloquia are usually very subject specific. When I did my PhD in condensed matter physics, d

This! For the programmers in the house, it would be like claiming you can code python if you’ve never coded before but watched some videos of expert teachers explaining the structure of python programming. I often see people here on HN sayi

I remember using the Old wooden escalators at Macys in NYC when I was little. And Looks like Macys even kept them after a recent renovation : https://mobile.nytimes.com/2015/11/26/nyregion/macys-histori..

“Using a modified 3-D printer, they injected threads of water into silicone oil — sculpting tubes made of one liquid within another liquid.” From the article, in case anyone’s curious how 3D printing of liquids works.

Glad to hear you say this!! I’m in the same boat, the flashing cyclist lights hurt my eyes and give me headaches. Sometimes I need to hold up my hand like the sun visor, to cover the flashing light. Other times I’m tempted to turn on my bri

Do people actually fall for this? I thought this is the whole reason to use the blue check mark, so you can immediately tell real Elon from bot Elon. But there are weird celebrity bots too. Eg, I followed Adam Sandler, and within a few hour

I’m a total Twitter n00b. But are we really supposed to retweet more than we like? I was treating retweets as a stronger version of ‘like’, in a sense. Assuming too much retweeting will clog my followers’ feeds, and make them more likely to

Replying to myself to make one suggestion : Twitter can be a useful tool too. I only started with Twitter a couple months ago. And soon found there are regular writing prompts. Eg - #1LineWed and #SciFiFri. These usually have a theme, eg to

Put some words on the page. Good or bad. You can fix it up later. In the past year I wrote a kids sci-fi novel. Well, I finished the draft, and I’ve been editing it the past few months. It’s something I’ve been meaning to do for years, but

This will be an unpopular opinion, but I strongly suspect you’re misremembering what became a common joke after the fact, just like the original article. I was also in 5th grade when the Challenger exploded. There was a slew of challenger “

I seriously hope you do the right thing and do NOT buy diesel. It would be incredibly irresponsible now that the dangers of NoX are known. FYI, I live in London and am seriously affected by NoX, I’ve had bronchitis several times in the pa

One suggestion - are you able to shift your hours to see your kids either before or after? I’ve been able to arrange things and arrive at work a bit later, so I see my kids each morning and take them to school. Then I stay a bit later at wo

I mentioned this a couple months ago, but here in London an Amazon courier left our item in the bin (ie, garbage can) in front of our house! Not even a friendly note thru the mail slot to say “we put your package in the bin”. Luckily my wif

I had something similarly weird with amazon. I got a new iPhone and on iOS Safari I needed to sign in to all my accounts. Except for some reason Amazon recognised me with one-click enabled. I never used one-click to buy anything before and

I used both Griffiths and Townsend’s books in undergrad QM classes, they complement each other nicely. It’s been awhile, but IIRC Griffiths starts off with a focus on continuous wave functions while Townsend starts off with spin and discret
