Experts Pick 1951's Biggest Science News
What was the biggest news from the laboratories and workshops of the scientists this year? If you were to ask 10 of America's best-known science reporters—as Popular Science has done—you would get 10 different answers to this question. The 10 journalists to whom the question was put are pictured below. All of them are members of the National Association of Science Writers. They cover science news the way Washington correspondents cover politics and police reporters cover crime. They have spent the past year interviewing scientists, attending scientific meetings and studying scientific reports to obtain the news of science for the readers of the newspapers, press associations and magazines that they represent. The stories that they consider this year's biggest news are summarized in the article that follows.

Here comes TV for everybody
The whole country, and not just a few metropolitan centers, will enjoy television when new ultra-high-frequency stations go on the air. IF YOUR home is outside the TV areas today, it is almost sure to be inside one within a few years. If you now can get only one or two stations, you'll have a wider choice pretty soon. Right now a total of 108 television stations are on the air. They all use waves from four to 18 feet long in the very-high-frequency range, called VHF. In the VHF range, only a few hundred stations can be fitted without interfering with each other.

Cats Are Fun to Photograph
An expert reveals tricks that help you get good pictures of Tabby. Patience is the biggest requirement. By Walter Chandoha CATS are easy to photograph—if you can tap an unlimited supply of patience. Beyond that, all you need is a camera (I prefer a reflex) with flash attachment. An assistant, portrait lenses, a tripod and a flash extension are helpful, but by no means essential.

Wanted: Science Talent
Scholarships await promising students who hurdle series of brain-busting tests. By David O. Woodbury MARINA PRAJMOVSKY came to this country from Finland when she was four. Her father was a Russian-born machinist, her mother a seamstress. While in high school at Farmingdale, N. Y., in 1942 she entered the first Science Talent Search, a competition held by the Science Clubs of America. Out of some 15,000 entrants Marina tied for first place. The Search's $2,400 scholarship got her started at Radcliffe. She graduated as the only sum ma cum laude in biology in the history of the college. In four years more she had a medical doctorate from Yale and now at 27 is doing research on eye diseases at Columbia-Presbyterian Medical Center in New York. Along the way she did highly secret work for the Navy and carried out outstanding research on DDT.

Atomic Clock Verifies Oldest Bible Manuscript
By James T. Howard They shall heat their swords into plowshares, and their spears into pruning-hooks; nation shall not lift up sword against nation, neither shall they learn war any more. —Isaiah II, 4. WHEN the atom bomb first mushroomed its message or death and destruction into the sky six years ago, there were many who speculated on the future uses of atomic knowledge. But few if any put Bible study on their list. Now, as Christmas of 1951 nears, we find the seeming miracle has come to pass. Science is revealed as the handmaid of religion; radioactive carbon-14 and the Geiger counter are instruments for casting new light on the accuracy of our modem Bible. Cosmic rays that bombarded the earth when Christ was born have left behind a coded message for nuclear physicists to decipher.

What Happens When You Mail a Letter
By Herbert O. Johansen With the Christmas rush on, the complex network of men and machines that speeds the mails is working in high gear. WHEN you drop a letter in a mailbox and hear the slot lid click, you probably give the lid a couple of extra flips for good measure. In return for that effort, plus licking the stamp, you take it for granted that your message of love, business, sorrow, cheer or complaint will be delivered to the right person at the right place in the shortest possible time. And it almost certainly will be—along with the other 127,677,738 letters that are mailed in the United States on an average day—enough letters, if their envelopes were laid end-to-end, to reach from New York to Shanghai.

Dial Switches Message Tubes
By Dialing a number, workers in a Connecticut factory can send written messages and even metal samples to various parts of the plant in about a minute's time. They are using the familiar old pneumatic tube, the hissing clanging gadget used to make change in many department stores. This pneumatic tube is different. Wehere older systems required separate tubes to each station, this one has an automatic dial exchange, just like a modern telephone central office, making a few tubes do the work of many. Each carrier has numbers that can be set to guide it automatically to any one of the nine stations that make up the first American installation at the Housatonic plant of the Bridgeport Brass Co. Eventually there will be 20 stations.
