Vad är det för skillnad på adjektiv och adverb? Adjektiven beskriver en sak eller en person, adverben beskriver ett tillstånd eller en handling. Heter det imperfekt eller preteritum? I många andra språk finns det olika former för imperfekt och preteritum för att ange om handlingen är fullbordad eller ofullbordad. Subjekt och predikat, vad är det? Subjekt och predikat är satsdelar, alltså byggstenar i syntaxen. De eller dem? Många tycker att det är svårt att veta när man ska skriva de och när man ska skriva dem. Var eller vart?

Scientists Make Headway Toward Invisibility Cloaking The world of science fiction is rife with examples of invisibility - whether it is Harry Potter’s cloak, Romulan cloaks integrated into a spaceship’s shields, or the One Ring that helped our favorite hobbits steer clear of orcs. Of course, actually creating a device that is capable of bending light so an object appears to be invisible to the eye is a fairly tall order. However, a group of materials scientists led by Debashis Chandra at the University of Central Florida have made significant strides forward to making this long-fabled device a reality. By using nanotransfer printing, the team achieved optical properties across a large swath of material that have never been accomplished on such a large scale before, breaking barriers toward the development of a cloak that could make an object appear to be invisible. The team was able to a 3D metamaterial from nanotransfer printing.
Modern Machine Shop Blog Blog This photo was taken by Todd Schuett of Creative Technology Corp. during Superior Tooling’s NCTAP orientation session back in March. The program’s stringent application process weeds out all but the most promising applicants before any commitment is made. A press release from Schunk recently caught my eye, but it didn’t have anything to do with the Morrisville, North Carolina, company’s workholding technology. In my view, the programs the Governor praised deserve all the recognition they can get. Back then, NCTAP was the program benefitting from the guidance of its peers. Apprenticeship 2000 has attracted attention from the highest levels of government. It seems fitting that, two years later, NCTAP members are standing alongside their Apprenticeship 2000 colleagues to similarly guide two more newly-launched programs (hence the aforementioned ceremony, which also recognized Apprenticeship Catawba and Siemens Charlotte for their leadership roles). 0 Comments 0 Comments Tool or die?
Death By Scrabble by Charlie Fish She plays SWEATIER, using all her letters. 24 points plus a 50 point bonus. If it wasn't too hot to move I would strangle her right now. I am getting sweatier. It needs to rain, to clear the air. As soon as that thought crosses my mind, I find a good word. HUMID on a double-word score, using the D of JINXED. She tells me she has lousy letters. She plays FAN, with the F on a double-letter, and gets up to fill the kettle and turn on the air conditioning. It's the hottest day for ten years and my wife is turning on the kettle. She sits back down with a heavy sigh and starts fiddling with her letters again. The rage gets to my fingertips and passes. She plays READY on a double-word for 18 points, then goes to pour herself a cup of tea. I steal a blank tile from the letter bag when she's not looking, and throw back a V from my rack. She asks me if I cheated. I really, really hate her. She plays IGNORE on the triple-word for 21 points. The steam rising from her cup of tea makes me feel hotter.
