Which should I prefer — a scanning disk or a cathode ray tube? This is perhaps one of the main issues facing developers of experimental television equipment. While the design of the scanning device is constantly being improved, the creation of a cathode ray tube is fraught with many technical difficulties. Anyway, people have not yet had a real opportunity to enjoy the benefits of television. It is not yet clear when television will become public and what kind of television equipment will it be?

In New York, a system was demonstrated at the scientific laboratories of Peck Television Corporation, which is believed to become a popular means of home entertainment in the near future. We are talking about a television device on the screen of which you can watch the footage of the current chronicle. The president and the leading engineer of this company U. Peck has developed a new type of scanning device for television movie transmission. There are no mechanical rotating elements in it. Photocells and two ordinary car headlight bulbs are used to generate audio and video signals. The device allows you to display images with a scan of 60 lines. Although the clarity of the image displayed on the screen is not very high, viewers could even follow the movement of baseball bats when showing a baseball game in close-up.

Finally, it became possible to produce vitamin C (ascorbic acid) on an industrial scale. The corresponding process (which is the world's first synthetic method of vitamin production) was discovered several months ago and is currently being developed and improved for mass production. This discovery was announced by the outstanding Hungarian scientist Albert Sant-Gyorgy at a meeting of the British Association for the Advancement of Science.

Henry Ford once stated that with the current level of aviation development, flight safety depends on 90% of the pilot's skill and 10% of the aircraft's reliability, and that until these numbers change places, aviation is not able to become widespread. This opinion can be supported by the fact that more than 50% of accidents on private planes are caused by the pilot. The Bureau of Commercial Aviation believes that it is currently possible to produce aircraft of this design, and in this ratio, technology will play a decisive role, with approximately 10% remaining for the pilot. The first step towards flight safety has already been taken. The Ministry of Commerce has announced an order for its own needs of 25 aircraft that meet the most stringent requirements for flight safety and ease of operation. The Bureau expressed the hope that as a result of competition between aircraft manufacturers, a new aircraft will be created, which the pilot will not need long and time-consuming training to fly.

Recently, there was a message about the creation of a new mixer with an autonomous electric drive for making ice cream. This ice cream maker can be inserted directly into the freezer compartment of a conventional automatic refrigerator. Since household refrigerators have become widespread, many housewives have needed such a device, so various companies have spent a lot of time and money on developing and improving an electric ice cream maker.
