For circuitry to be able to detect something, that something has to be giving off some sort of energy such as radiation or an emission of a frequency, or has to be able to reflect some sort of energy back from the circuitry such as a pulse of light or sound wave. Even gas detectors including smoke alarms follow this principle as they work by monitoring the ...

Question: Can food type have any effect on weight loss even though net calories would remain constant? Answer: Yes. When you start a low-carb diet (for example < 50 g carbs/day), within the first 1-2 days, your body glycogen stores (about 500 grams) are depleted. Every gram of glycogen is bound to about 4 grams of water, so along with glycogen ...

Whether voting via the Internet could be made "secure" depends upon what is meant by the term.

The design of the symbol itself has been described in great detail, up to the color palette.[1] However, font designers have made it clear that they were going to design their own variants,[2] and they did[3], and I could find no records of any font designer having ever been sued over the (mis)representation of a currency symbol.

No and here is why. The conservation of mass has already been mentioned. Because we are dealing with chemical processes, mass-energy conversion is completely neglible.

According to common sense, the hair is a dead cell with no nerves. The brain / body couldn't possibly know whether the hair is there or not.

So the answer is no, hair growth cannot be ...

You can think of the seven colors as being nodes in the spectrum of visible light, those which are striking enough for human beings (at least English-speaking ones) to have assigned names. There are other colors, of course, even named ones, but those stand apart from the familiar named colors of the spectrum. The rest of the gradations are continuous tones ...

田原坊 「松島や さて松島や 松島や」 松尾芭蕉が『奥の細道』で松島を訪れた際に、あまりに絶景なので句が浮かばず、「松島や ああ松島や 松島や」という句を詠んだという逸話があるが、実際は後世の狂歌師の田原坊の作とされる。ただし、その場で句が思い浮かばなかったのは事実らしい。また別の説では、句は詠んだが景色に釣り合うよいものができなかったともいわれる。なお、小説家の司馬遼太郎は、紀行集『街道をゆく』「仙台・石巻」にて、「松島や ああ松島や 松島や」の句が芭蕉作として松島の看板などの観光資料に記されていることに対し、松島の観光関係者を批判している。 According to the above, Matsuo Basho did in fact visit Matsushima on his trip to ...
