So even during the time from R1 to R2, you saw a really big upgrade in the sensors that we had on the vehicle and the same thing is happening now from R2 to the Nuro, is a massive upgrade, both in the capabilit
This is the story of how the MIT Rad Lab—formally named the MIT Radiation Laboratory to confuse the Nazis—was charged with using that top-secret British invention to design, build, and field-test advanced radar equipment that would pave the way for the invasion that helped win the war. I...
This augury of the office network came to him in 1950, in an era of room-sized computers, vacuum tubes and punched-tape programming [sources: DEI; Markoff; MIT]. His stint as a radar technician in World War II had convinced him of the potential uses of screen displays, but how to ...
Even things like radar and microwave ovens depend on radio waves. Communication and navigation satellites would be impossible without radio waves, as would modern aviation — an airplane depends on a dozen different radio systems. The WiFi networks that we depend on at work, home and school also...
To understand how radar detectors work, you first have to know what they're detecting. The concept of measuring vehicle speed with radar is very simple. A basic speed gun is just a radio transmitter and receiver combined into one unit. A radio transmitter is a device that oscillates...
Using a theoretical, model-based approach, this study is the first to examine multiple types of technosignatures together rather than separately. The findings show that Earth’s most detectable signals come from radio emissions—particularly planetary radar, such as those once transmitted by the A...
But how do we get the sails and their spacecraft into space? Let's take a look. You want holes in the sail? Les Johnson, of Marshall Space Flight Center, holds a rigid, lightweight carbon fiber material that gave many solar-sail-scientists pause for thought. This fiber was a departure...
FM radio was invented by Edwin Armstrong in order to make high-fidelity (and static-free) music broadcasting possible. He built the first station in 1939, but FM did not become really popular until the 1960s. Hence the higher frequencies for FM radio. Radio Frequency Scanners Most radios ...
Did the Han dynasty invent the seismograph? How was Charles Richter introduced into the field of seismology? Who began the study of seismology? When was the seismometer invented? What do S-waves look like on a seismograph? Who invented the Doppler radar? How do seismic waves give scientists ...
It’s still the land of opportunity, but now it’s confronting the human cost of its success. The new buzzwords: responsibility and empathy.
