Hopper, that is

Military robot ‘hops’ over walls

Most of the time, the shoebox-sized robot – which is being developed for the US military – uses its four wheels to get around.
But the Precision Urban Hopper can use a piston-actuated “leg” to launch it over obstacles such as walls or fences.

The ad in the video is longer than the video, but it’s worth the 30 seconds. The slow-motion replay really needs the bionic sound effect from The Six Million Dollar Man to complete the experience.

There is no Fun in Funding

Real Lives and White Lies in the Funding of Scientific Research

K.’s plight (an authentic one) illustrates how the present funding system in science eats its own seed corn [2]. To expect a young scientist to recruit and train students and postdocs as well as producing and publishing new and original work within two years (in order to fuel the next grant application) is preposterous. It is neither right nor sensible to ask scientists to become astrologists and predict precisely the path their research will follow—and then to judge them on how persuasively they can put over this fiction. It takes far too long to write a grant because the requirements are so complex and demanding. Applications have become so detailed and so technical that trying to select the best proposals has become a dark art. For postdoctoral fellowships, there are so many arcane and restrictive rules that applicants frequently find themselves to be of the wrong nationality, in the wrong lab, too young, or too old. Young scientists who make the career mistake of concentrating on their research may easily miss the deadline for the only grant they might have won. Research institutes with their own funds can solve these problems, but grant holders like K. do not have any flexibility. The real world of science has no tidy banks of pigeonholes, each one occupied for a standard period by an exemplary student or a perfect postdoc.

The List of N Things

Some of the work of reading an article is understanding its structure—figuring out what in high school we’d have called its “outline.” Not explicitly, of course, but someone who really understands an article probably has something in his brain afterward that corresponds to such an outline. In a list of n things, this work is done for you. Its structure is an exoskeleton.

As well as being explicit, the structure is guaranteed to be of the simplest possible type: a few main points with few to no subordinate ones, and no particular connection between them.

Because the main points are unconnected, the list of n things is random access. There’s no thread of reasoning you have to follow. You could read the list in any order. And because the points are independent of one another, they work like watertight compartments in an unsinkable ship. If you get bored with, or can’t understand, or don’t agree with one point, you don’t have to give up on the article. You can just abandon that one and skip to the next. A list of n things is parallel and therefore fault tolerant.
