To create randomly distorted knots, we compute a random normally distributed vector, δ, for each point in a polygonal representation of the vortex knot in question. We then smooth this vector with a Gaussian of width σ = 0.5r0 (measured along the path of original vortex line), remove the...
The first generation of post-iPhone devices consistently featured screens under four inches (as measured across the diagonal), an easy size for one-handed use. By mid-2014, however,a third of mobile web-browsing took place on larger screensas bigger phones shouldered into the marketplace. These...
Scientific testing has shown that trout have color vision, and has even measured how faint a color can be and still trigger a response from the fish. It is often said that we can’t know what a fish sees, but that’s also true of other humans. When I view the Stars and Stripes, ...
First, the force spontaneously applied on sutures during experimental knot tightening ("tying load") was measured in fifteen experienced surgeons. Second, with each suture material, surgical square knots were tied with increasing, standardized loads (range 0.5-50 N) using a custom-made apparatus. ...
the log would be thrown into the water and trailed behind the ship. The number of knots that passed off of the ship and into the water over a certain amount of time would be counted and the number counted determined speed in “knots.” Present-day knot measurements are determined with mo...
drinking, and what you did after the last concert, tend not to appear on these shameless plugs. I wish I had a copy of my own self-promotion that got me in the door; I'd be curious to see, twenty years later, how I measured up to the ideal version of myself that I wrote ...
And second, the trunk wouldn’t be large enough to pack all the stuff we would need for the long day trips we would be taking from Baker City. My first thought was to pack the saddlebags full of clothes and pack the packed saddlebags in the luggage, but they were too big and too...

Okay, who cares about that first part of the study, those people were already fine, it didn't hurt to buzz 'em about a bit and see if anything happened. What about the subjects who actuallyhavelymphoedema? Well, there are plenty of graphs in the, deep breath, "secondary lymphoedema and...
“Health officials on Friday confirmed bird flu in a California child — the first reported case in a U.S. minor. The child had mild symptoms, was treated with antiviral medication and is recovering, the Centers for Disease Control and Prevention said in announcing the test results. State off...
