It's calculated by assuming you will get the same weekly wage for a year. The tax office produces some tables employers can use as a guide, so if weekly wage is $x, deduct $y as the tax component. I guess any extra pay (overtime, bonuses etc) is paid at your marginal tax rate.

If you have a second job, that job is meant to tax you at the top tax rate, so the tax office gets an excess of your money and returns it to you when everything is reconciled at the end of the year (by submitting your tax return).

When I had my Appendectomy (old style, not key-hole) I woke up 8 hours afterwards and had zero pain!

It never hurt once, even though the nurse told me they were authorised to give me pain relief all the way up to morphine if I needed it. I assumed they gave me something after the surgery which hid the immediate pain for a day or two.

Khyber, can you share some ballpark figures on what would be required?

How low-power can the illumination be to keep the plants healthy during the two week lunar night? Something below full sunlight like 250 W/m2 for 12 hours a day?

The article says 50 sqm is required for a single person, so to last two weeks that would require 2,100 kWh of batteries. That would take the battery packs from 25 Tesla Model S cars with a weight maybe over 10 tonnes?

I think the bitterness seems to only really kick in at the end of extracting a coffee shot.

I find that if I run my espresso machine for 24 seconds I get a good shot of coffee, but if I run it for 28 seconds the shot is very bitter.

No I can't, his website is blocked for international viewers (and I'm in Australia).

I too will need a VPN...

Perhaps the aircraft should be a drone? Then no humans would be at risk, plus it might prove marginally cheaper to operate and save on dead weight.

The LHC has 8 teraelectronvolt collisions, with that extra energy making it many times more likely that a 'fragment' of the collision will have the 125 GeV needed to form the Higgs Boson.

Do you know if he's sharing what you've shown him with his school friends? You might have a chance to influence a few more children than just your son.

You could do what the ancient Romans did and brand a 'false accuser' with the letter K on their forehead!
