dropping your FB account is not enough

FB is insidious (darth insidious even)

1> start a new browser profile (copy bookmarks across but not FB or Inst..)

2> BLOCK all cookies from FB and associated companies

3> block using "No Script"™ or similar the FB & Inst... web sites

4> block using "Ghostery"™ or similar the FB & Inst... web sites

5> for extreme paranoia set FB address to 127.0.0.1 (not recommended)

Re: ' Current industrial production of hydrogen gas'

this missed one important point, the tank needed to have stored hydrogen for a year at pressure and near full before the test. A new tank may well pass but an old one will not.

Not really near

Proxima Centauri is about 248 300 ± 350AU from Sol and Earth and so far the furthest Earth has been able to send an operation space craft is 40 AU and that has taken decades, so not out of the error bar on the length of the trip.

I built a hovercraft as part of my engineering degree, they are an interesting machine but physics is not kind to them.

They have a problem going up hills (similar to trains) as low as an 6% slope will stop them and they are very noisy.

Re: Ummmm

A better measure of distance would be AU and T-Ceti is about 794 000 AU away and remember the Voyager probes launched many years ago have travelled 40 AU

What about wombats

Wombat are much more dangerous than kangaroos and they win in a truck vs wombat encounter.

Re: Feeling torn

There are many points about the paper, which are awkward.

1 - Unusual journal for radio astronomy, (significant issues with the authenticity of the journal and its referees)

2 - Use of units of signal strength from comms not radio astronomy

3 - No mention of location, background contamination data no supplied/measured

4 - Heavy use of person resume

5 - Minimal calibration data

6 - Insufficient data to reproduce the comet data

7 - et alia

One or two of these can be overlooked if the others are present, but not all of them. Go read the reddit post for a full description of the short comings of this paper.

Puny galaxy packs a big punch: A gazillion joules' worth of radio bursts

That is big

So 10 million trillion trillion joules = 1*10^31 J (a joule is tiny but 10^31 of them is not) and for a more "leReg" style unit, a kilo of hydrocarbon fuel is c40MJ, so this is 2.5*10^23 kilos of fuel or as Avogargo's number is the same order of magnitude, this is 0.4 (Avogargo's number) * (kilos of hydrocarbon fuel[such as petrol]).

Chinese boffins: We're testing an 'impossible' EM Drive IN SPAAAACE

hekla
Holmes

Ridiculous power for a result

The EM-Drive uses a ridiculous amount of power for a result that is still not proved as statistical noise is bigger than the effect.

For an EM-Drive to balance against gravity on Earth at sea-level (in vacuum if you insist) a small coin (such as 5p or 10c) it takes the power output of a medium national grid connected Nuclear Power Station.

So Schrödinger and others suggest that a real result of force is yet to be achieved.

They should check out wombats as well

These are nocturnal with dark fur about 50 kg also about 600 mm at the shoulder, so walking rock. Not likely on suburban roads and will flip a truck or take out the steering and brakes on a car (and some will say they walk away after the hit).

Got off lightly

This seems to be a very benign OH&S induction.

On one work site it required 2 half day sessions one in the PM and the other the following morning.

The questions on the test did not have obvious answers and some of the building contractors were failing on the first test and doing it again.

The plant was not operational, so the other 3 half day sessions were not required, on starting operation it would be back to the beginning and do all 5 sessions.

OH&S induction needed to be completed and signed off before access to the work place was allowed. I have heard there was one site with an 8 session induction.

1: Get rid of the exploding nav-bar.

2: Custom colours for read and unread stories. Browsers are designed to set these, so it is extra effort and COST to set them as well as a source for errors in coding.

Size matters – how else could Dell squeeze 15 million pixels into this 27" 5K monitor?

hekla
Angel

Too smaller pixels to be relevent

Eyesight has its limits and it is expressed as 152 400 (divided by) pixels per inch and gives the distance in millimetres, beyond which the individual pixels are discernible by young eyes (make the number 101 600 for old eyes).

So anyone sitting more than 700mm from this screen will have a "retinal" display and most of their field of view taken with this display.

Why your mum was WRONG about whiffy tattooed people

hekla

a cuff would be good

a suggestion would be an arm cuff around the bicep which could hold the mobile phone and by the skin contact give a little power to the phone.

A phone battery hold (1500 mAh at 5V) about 25 kJ of energy.

This tat gives 70 microWatts per cm2, now a bicep wrap could give 300 * 100 mm2 or 300 tats and thus 21 mW (that is milliwatts).

So 25kJ means that at 21mW a full charge takes 357 hours.

system would need some more work (in both meanings).
