In January of 1954, supported by the military, engineers from Bell Labs built the first computer without vacuum tubes. Known as TRADIC (for TRAnsistorized DIgital Computer), the machine was a mere ...

The scientists Aylesworth talked to suggested there were probably additional impurities in the tin to make that first transistor work. So instead of the tin-doped germanium, Aylesworth used a ...

about six years after Texas Instruments and Regency introduced the first transistor radio. Unlike traditional vacuum-tube televisions, which were bulky, fragile, and power-hungry, the TV8-301 was ...

In 1947, the first transistor, the basic building block for a digital computer, was made using a semiconducting material thought to be ideal for the task: germanium. The idea of using silicon didn ...

the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the first silicon chips used bipolar transistors, most chips today use field-effect transistors wired as ...

American inventor Samuel Morse transmitted the first long-distance telegraph from Washington, D.C., to Baltimore: “What hath God wrought?” Besides ushering in the age of instant long-distance ...

Scientists in the US built the first silicon transistor in 1947 ... “All because we can put a massive computer onto a tiny chip.” The pace of innovation was unprecedented.

American inventor Samuel Morse transmitted the first long-distance telegraph from Washington, D.C., to Baltimore: “What hath ...
