To economists, prices serve as crucial signals to producers and consumers. In a regulated market, the state sets prices high enough for private companies to cover their costs and earn a guaranteed profit for their investors. But in a deregulated market, prices should vary with demand and supply.
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.
My central thesis is that combining increased temporal and spatial resolution in MRI techniques with increasingly powerful data correlation techniques will allow the derivation of interpreted meanings from neural signals. I observed, further, that the techniques that exist already allow some correlations.
The relentless invisible storm of radio signals and electronic particles, the hustle and bustle, and the billions of petrol explosions in the engine blocks of trucks and cars seem to churn up the molecules of life and heaven so violently that the beautiful fogs are unable to hold together like they once did.
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.
Radio astronomy reflects our fascination with how audio can be used to understand information or ideas. Just as scientists visualize data through charts and pictures, we can use 'data sonification' to translate radio signals into sound that help us better understand some of our most enigmatic planetary systems.
Cancer cells have a lot of other things that are really wrong with them, and we should never forget that these are cells that have become deaf to all the signals that the body sends out, such as you can multiply a certain amount, you can be in a certain place in the body, where to stay, where to move, and so on.
And I think at the end of my life, it's not going to be about what I did for myself, but what I did for others. Maybe it's staying after practice to do hand signals with the guys to help them get caught up to speed. To make it about others - I think that's what leadership is all about, quarterbacking is all about.
Cancer cells come pre-programmed to execute a well-defined cascade of changes, seemingly designed to facilitate both their enhanced survival and their dissemination through the bloodstream. There is even an air of conspiracy in the way that tumours use chemical signals to create cancer-friendly niches in remote organs.
At 3-D Imax theaters, audiences have shown they are willing to pay a premium to wear headgear fitted with liquid-crystal lenses synchronized via infrared signals with the movie projector, which runs at twice the normal frame rate. These movie viewers plumb new depths in depth perception - they experience extreme realism.
The cosmic game changed forever in 1992. Before then, logic told us that there had to be other planets besides the nine (if you still count poor Pluto) in our solar system, but until that year, when two astronomers detected faint, telltale radio signals in the constellation Virgo, we had no hard evidence of their existence.
Part of my advantage is that my strength is economic forecasting, but that only works in free markets, when markets are smarter than people. That's how I started. I watched the stock market, how equities reacted to change in levels of economic activity, and I could understand how price signals worked and how to forecast them.
You can never hit someone to the body and cause them to go unconscious. To be hit in the body is an unconscious experience that one has to endure. Signals of pain shoot instantly from you liver to your brain telling you how uncomfortable it is to be in that situation. Then it's up to you to find out if you can stand up or not.
The 'old' Internet is shrinking and being replaced by walled gardens over which Google's crawlers can't climb. Sure, Google can crawl Facebook's 'public pages,' but those represent a tiny fraction of the 'pages' on Faceboo, and are not informed by the crucial signals of identity and relationship which give those pages meaning.
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.
We curate our lives around this perceived sense of perfection, because we get rewarded in these short term signals: Hearts, likes, thumbs up. We conflate that with value, and we conflate it with truth, and instead, what it really is is fake, brittle popularity that's short term and leaves you even more vacant and empty before you did it.
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.
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.
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.
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.
