Ken Ham’s Ark

Oh I do like this one, via Chuckles, who headed it: “James at Work”:

Ark-Building Creationist Explains Why It Was Totally Cool

Yo, c’mon you Creationists, ra, ra, ra. Huffington Post, home of the godless and leftist:

Ken Ham, the creationist behind the giant Noah’s Ark replica nearing completion in Kentucky, received some pointed questions on Twitter from those who have a problem with the central message in the biblical story. 

Ken Ham?  Excellent name, excellent.  Naturally, the narrow-minded Huffposters who believe in nothing beyond their eyes see all sorts of nefarious doings in this on the part of God and they’ll find the kookiest individuals who claim to be Christian and make fun of them, just as the left does with the GOP RINOs who are not real conservatives.…

Not total honesty on safety railings

Just woken by the neighbours’ noise again, TV blaring at 3 a.m., do not need it. Anyway, that’s sleep for sometime. Writing this at 3.30 a.m., shall post it at 13.30.

Looking again at that pic from the top of the What’s Wrong post [think we could gaze on that for some time, those of us actually past it, LOL]:

anything wrong here

… it seems it’s an old boat which has been refitted, so why the missing safety wire is a mystery – but it’s more even than that.…


It was either another post or some music. Let’s have the post now and the music tomorrow morning.

In 1932, the Dutch astronomer Jan Oort tallied the stars in the Milky Way and found that they came up short. Judging by the way the stars bob up and down like horses on a carousel as they go around the plane of the galaxy, Oort calculated that there ought to be twice as much matter gravitationally propelling them as he could see.

He postulated the presence of hidden “dark matter” to make up the difference and surmised that it must be concentrated in a disk to explain the stars’ motions.

But credit for the discovery of dark matter—the invisible, unidentified stuff that comprises five-sixths of the universe’s mass—usually goes to the Swiss-American astronomer Fritz Zwicky, who inferred its existence from the relative motions of galaxies in 1933. Oort is passed over on the grounds that he was trailing a false clue.

The one sail they never modernized

The eminent [in sailing circles] CA Marchaj conducted a series of tests decades ago on the little known [outside of the South-Pacific] characteristics of the crab claw rig.


Similar things happened with the Chinese lug or the junk rig. All sorts of improvements were suggested, built and tried but some of the characteristics which really counted were lost in putting those rigs onto a western boat.…

The four-stroke engine

From Animagraffs:

Did you know that your car will take in 20,000 cubic feet of air to burn 20 gallons of fuel? That’s the equivalent of a 2,500 sq. ft. house! If your only experience with a car engine’s inner workings is “How much is that going to cost to fix?” this graphic is for you. Car engines are astoundingly awesome mechanical wonders. It’s time you learned more about the magic under the hood!

Driverless vehicles – what could possibly go wrong?

Oh my goodness, what could possibly go wrong?

This morning, a fleet of self-driving trucks arrived in the Dutch port of Maasvlakte, completing a cross-continent journey that organizers say demonstrates the future of transport in Europe. The experiment is known as the European Truck Platooning Challenge, and involved trucks from six different manufacturers traveling in miniature convoys.

A driver in the lead vehicle of each convoy sets the speed and the route, while the other trucks follow automatically, a Wi-Fi connection keeping their braking and acceleration (but not steering) in sync.

This isn’t a fully-automated system, but it’s a clear step toward this goal and has tangible benefits of its own. Platooning, as the method is known, could mean less congestion, fewer accidents, and reduced fuel consumption.

whitepaper from Dutch research firm TNO says that each truck in a platoon — both those following and those leading — uses on average 10 percent less fuel per journey.

The rig reviewed

square rigger and moon

While it’s not vitally important I decide today final details of rig, as firstly the mast points are now set, reinforced and can’t alter and secondly, the boat is for canal initially, so that gives me time – while it’s not critical to finalize rig, it would help if I put the sheet points now rather than later, so i know what reinforcement it will need.…
