Cameras only see one colour per pixel (i.e. Bayer colour filter array). Because our eyes are not so acute at resolving colour compared to luminescence this tradeoff works well. But…

There is a real, if small, chance that there could be a general election in the UK soon and potentially a more favourable labour government. If I were Assange I would do whatever I…

Yup it did - I was flying aerial surveying at the time. Bad timing. Actually I didn't notice anything in the end so was all good but when I saw the NOTAM I couldn't believe my bad …

No I don't, my calculations at this stage are as follows: Sail area - same as my 10 ton boat. Gets me to 7kts in a good strong wind. Boat they intend to install it on: 110000 tons!…

I understand that, in fact probably uniquely to people on this thread I've been on a rotor sail boat (not sailing though, in dock). They do work when the ratio of the sail area to …

I build camera gear for 172s and fly (as passenger, not pilot) probably 20-30 days per year, sometimes much more, and I get nervous at 40kts IAS is I guess around the full flaps st…

Very thought provoking. I'd like to add that this could be the case 'subconsciously' without him realizing or rationalizing it to himself.

Comment #17887413
My small 12 meter long boat has a sail area of 900sqft. When sailing perpendicular to the wind it captures pretty much all of that. The sail on that ship is 100' high, and looking …

Thank you, excellent points amd compelling argument. My point however remains - 99.999999% pure makes 100.000% sense. Ultra pure does not.

I didn't realise the word pure was context sensitive. OED doesn't either, perhaps you could contact them and help them update their definition: https://en.oxforddictionaries.com/de…
