Even the deaf percussionist Evelyn Glennie says that he said "woman". She is a master lip-reader. I'm good but she's awesome.

Does your browser clear cookies on exit or not accept them? You need to create an exception if it does either. Annoyingly, it is EU law that acceptance is required. Maybe it's just started complying with this update.

If the rate you are freefalling continuously increases with time, how is that not acceleration? Is it not called "acceleration" because an external force has not been applied, and it is a specific word requiring specific conditions to be called acceleration?

Einstein never presented his intuition in the raw unrefined, unevidenced state to his peers, as many noobs do here.

Only on your first day: it's to deter spammers.

I meant within the metal itself but, yes, a variable thermal environment will likely loosen things in a structure.

I was just thinking of permanent effects TBH,

i don't think it will have any effect. It's not hot enough to affect its temper (hardness), if it has one, and it doesn't get cold quick enough (quenching) to affect it that way either,

Argument from incredulity. I have personally heard women say it on at least two occasions... as an identifier.

I was going to post this earlier but didn't, which aligns with your perception:

Yeah, even if I'd disagreed with him I'd have still plussed it. I like it because there's no SJW-whining undertones.

The 'truth' is what works for a given application.

Good, make it the beginning of his journey.

If it interests you, but I'm not going to first check someone's sexual history before I start reading up on quantum mechanics

We should just admire them for whatever they excelled in and leave the rest of their behaviour to the recycle bin of history; everybody's got skeletons.

I think there was a big dollop of sarcastic humour there.

No problem. If he was profoundly deaf then sign language is probably the way to go but I think him getting proficient in lip-reading would benefit him greatly and as long as he makes a point of saying to people that he needs to see their face when spoken to, he should interact quite smoothly with normal-hearing people as he matures. As he progresses, he should be able to seamlessly integrate the words that he sees in peoples mouths and expressions into sounds in his head, coupled with what he can hear... my brain actually seems to fill in the gaps I can't hear with sound... it's strange, but my brain definitely synthesises sounds and words in the gaps. My life has not been too bad socially in my adult years with respect to my disability and maybe your nephew can benefit from going in the same sort of direction. Given that he's four, I'm optimistic for him that medical progress will eventually give him unaided better hearing while he's still a young adult.

Hmm, a candidate ripe for the wrath of the MeToo movement then.

Ontologically, in physics, what a thing 'is' is its properties.

Note this is in the Relativity forum.

Hearing aids because I'd have been buggered without them. Second, the internet because I can drown myself in information.

Space is volume and volume is a property of things. Empty space does not exist as a distinct entity, just like 'length' doesn't. Vacuum energy is the lowest energy state a volume can have ( filled with virtual particles) but it's not zero i.e it is not 'nothing' or empty.

If you can, find him somebody who is proficient in lip-reading, which will fill in any gaps in what he can't hear. A teacher with that skill would be great. I had one. Given that he seems to have some hearing, like myself, i think he will find it a very useful tool when it gets a bit noisy and he'll pick up subtle cues about vocal inflection and how others are feeling through being able to read their faces. It will give him a better sense of empathy for people. Tonal inflection through hearing is beyond what a hearing-impaired person can pick up. Also notice that he will tire much more easily in a social situation because 'hearing' what a person is saying from deaf person's perspective requires a lot of conscious effort. It gets easier as one gets older.

Try erasers on pencils cut to the optimum shape, then clean with isopropyl alcohol-soaked cotton tips to remove eraser residue off contact surfaces.
