I went in, and there, in the front room, a converted bedroom, sat the first radio I had ever seen. The equipment was so bulky that it took up one entire wall of the bedroom. The set, which could send or receive signals, was tuned to KDKA in Pittsburgh, and I remember being completely flabbergasted at the thought of sounds coming from that box.
Health messages are simply overwhelmed, in volume and in effectiveness, by junk-food ads that often deploy celebrities or cartoon characters to great effect. We may know that eating fruits and vegetables is good for us, but the preponderance of the signals we get - and especially the signals children get - push us in the direction of junk food.
Governments must address inconsistencies in their energy strategies, consider the links with broader economic policies, and stop sending mixed signals to consumers, producers, and investors. In particular, they must assess whether the right regulatory arrangements are in place to allow clean-energy investments to compete on a risk-return basis.
Wilderness trails constitute a rare space in America marked by economic diversity. Lawyers and construction workers get bitten by the same mosquitoes and sip from the same streams; there are none of the usual signals about socioeconomic status, for most hikers are in shorts and a T-shirt and enveloped by an aroma that would make a skunk queasy.
The technology that lets many people use the same radio channel at the same time is called smart antenna technology or adaptive array technology or interference mitigation. This technology uses computer processors to take the signals from multiple antennas at each location and sorts the various signals out so they don't interfere with each other.
Plumage features constitute a major component of courtship signals.
I'm certainly not a person who spends their every waking moment soaking themselves in signs and signals of the sort that cult studies people study; and it's partly, I suppose, because some of those signs and signals aren't worth bothering about. You have to be selective about these things.
Business development is a part of M&A - we identify signals in the market, whether its trends or disruptive technology, and bring them back and address the opportunities. I have three levers I can pull - partnerships, acquisitions, or investments.
We started all this research way back in the early 1990s, developing a technique that allows us to record the electrical signals produced by neurons simultaneously.
Blushing is thought to be linked to increased levels of norepinephrine in the brain, which may be associated with romantic feelings. It signals that we are interested and excited, which is attractive to men.
Wherever information gathers and flows, two predators follow closely behind it: censorship and surveillance. The case of digital money is no exception. Where money becomes a series of signals, it can be censored; where money becomes information, it will inform on you.
I wrote my first play at the age of 10, 55 years ago, and I've always found it a fantastic relief to imagine I know what things would be like from the point of view of other individuals and to send out signals from where I actually am not. Playwrights never need to write from the place where they are.
With 'Smoke Signals,' the character was so much like me growing up. I lost my parents, and I wish I'd had an opportunity to find out where they were. So I was reflecting on how I grew up, that feeling of abandonment. That whole film was a reality that I always held back and kept to myself.
Television is ephemeral, a fact that some will find reassuring. But earthlings will continue to pump the kilowatts into the ether. And eventually, when those signals have washed over a few hundred thousand star systems, someone may notice.
Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.
Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male signals.
The total funding of SETI (the Search for Extraterrestrial Intelligence) in the U.S. is 0.0003 percent of the tax monies spent on health and human services. And it's not even tax money. The SETI Institute's hunt for signals is funded by donations.
To summarize, the particular song a male sings, and the behavioral responses of females to song and morphological signals, are not genetically inherited in a fixed manner but are determined by learning early in life.
Junk, redundancy, and inefficiency characterize astrophysical signals. It seems they characterize cells and sea lions, too. These biological constructions have lots of superfluous and redundant parts, and are a long way from being optimally built or operated.
Ever since the Second World War, television signals (as well as FM radio and radar) have served as Homo sapiens' emissaries into deep space. High-frequency, high-power broadcasts have filled an Earth-centered bubble more than 60 light-years in radius with signals.
The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years.
