why do stars look like they are moving

Do stars follow us, because one day I was looking in the sky and it seemed that way? If by "follow us" you mean that if you're driving down the street, you should see the stars remain in the same position in the sky even though you're moving, the answer is yes. The stars are much much much farther away than any distance you can move on the Earth, so you shouldn't be able to see them "move" on the sky just by moving on the Earth. One thing to keep in mind, however, is that the stars do move slowly over the course of the night. ...

why do we need to learn grammar

Why do we need grammar? ItБs not often that the word БinspiringБ is used to describe a day of grammar talks, but I was not the only one to think so at last weekБs English Grammar Day at the British Library. With a queue out the door and tickets sold out, itБs clear that grammarБs back. After years of absence on the National Curriculum, 2014 is the year when grammar will reaffirm itself on the. This is a cause for celebration. But why? Until very recently, education without grammar was unthinkable and, as I discovered in the first seminar of the day, the learning of grammar has an incredibly long and global history. Verb tables inscribed in tablets have been discovered that were used in Babylon in 2000BC. Many other civilizations of the ancient world were intellectually curious about how

 why do narcissists lie all the time

why do narcissists lie all the time

Crazy making. Truth is my head is still spinning. It's not a good idea to go ahead and read someone's journals or their rehab journals or??? But in this case I'm glad I did. Been with this gal for 4 years and we were engaged. She broke it off with me actually and then my behavior was sort of inhuman. I wanted her back so bad it paralyzed me. All my friends and family were trying to get me to understand why she wasn't good for me but I kept defending her saying "but I see that little girl in her dying to come out and I have so much compassion for her". But the reality is and I'm still going over it in my head which is still spinning-she is a true narcissist and victim. I can't even describe how she broke me emotionally, mentally, physically, and spiritually. I feel like I have been

 why do we have night and day on earth

why do we have night and day on earth

The Earth takes 24 hours to make one complete turn. Why do we have day and night? We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles. The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed. How long does it take the Earth to turn around? The Earth takes a whole day (24 hours) to makea complete turn. Why is the Sun in the sky at some times and not at other times? At any time half of the Earth faces the sun. This part has day.

why do we need your email address

security-sensitive (eg forgotten password reset token), or recurring/high-quantity, to avoid harassing some other person whose address has been entered. This is typically more about weeding out incorrect addresses that have been entered by mistake than some malicious attack. If you never intend to send mail to the address, you're only really using it as a fixed-format username and there is no particular need to validate it. But I would imagine that's an option you probably want to keep open. E-mail validation is not about rate-limiting sign-ups. It's totally ineffective at this for anything but low-motivation/untargeted attacks, because there is no scarcity factor on e-mail addresses. It's trivial for an attacker to register some domains, use unlimited random e-mail addresses on them,

 why do some fish have more mercury

why do some fish have more mercury

How Does Mercury Get into Fish and Seafood? Many types of fish are rich in omega-3 fatty acids that have been linked to a number of health benefits, but some popular species, such as swordfish, king mackerel, shark and some tuna, contain significant levels of mercury. At high levels, mercury exposure can harm the heart, brain, lungs, kidneys and immune system of people of all ages, and even at relatively low levels, it can harm fetuses, infants and young children. But how does this toxic compound get into fish in the first place? The high levels of mercury found in fish like swordfish, king mackerel and certain types of tuna are primarily caused by industrial mercury emissions around the world, with coal-burning power plants being the largest human-caused source of mercury emissions to

 why do salt crystals form on the skin cystic fibrosis

why do salt crystals form on the skin cystic fibrosis

Cystic fibrosis is a disease known for causing lung disease and serious illness beginning from babyhood or early childhood. Its pathogenesis, however, has to do with salt transport, and even before the disease of cystic fibrosis was defined, folk wisdom held that children with salty skin would become direly ill. Cystic fibrosis is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The protein coded by CFTR is an ion channel--a protein that regulates the passage of salt into and out of a cell. The CFTR protein maintains a balance of fluid and salt in the cell. When a mutation occurs in the gene, CFTR functions poorly, and salt is not transported properly. In people with two copies of the mutation, the clinical features of cystic fibrosis develop.
