Storm approaching the West Coast of USA? People of the East Coast can run to the grocery stores to buy bread, milk, eggs, and toilet paper—apparently modern humans’ idea of necessities—because models of the unseen can predict their weather.
In fact, we know much about the formerly invisible world. We can see the universe in radio and microwaves, infrared radiation, ultraviolet light, X-rays, and gamma rays. We can overlay images of all of them if we wish, making an image once impossible to see. And we can see Earth’s interior through seismic tomography so we can map magma chambers and other underground features that can help in predicting earthquakes and volcanic eruptions.
True, what we “see” is usually a computer-enhanced image and not a “photo-image,” but we “see,” nevertheless. And seeing in whatever form makes a difference in living, especially when it lends itself to forecasting and understanding.
Now, we are in the midst of a search for “seeing” into the brain, not just mapping it, but actually trying to see thoughts. I’m thinking of studies done by people like Professor Jack Gallant at the Henry H. Wheeler, Jr. Brain Imaging Center at UC Berkeley. Professor Gallant and others scan brains of people watching movies and then develop algorithms that produce images similar to, but fuzzy and blurry, what the watchers saw. * Gallant’s lab people work on constructing a computational modeling framework for brain mapping with the aim of faithfully decoding what goes on in the brain. They want to “see” thoughts.
Lots of these gizmos for seeing the formerly unseen are rather large objects or collections of objects, even in an age of miniaturization. Seismic tomography requires multiple sensors, for example, and Gallant’s brain scans occur in fMRI tubes not designed for the claustrophobic. But miniaturization is the current trend, so there might be a wearable brain scan and image projection system that is quite portable, that would enable the rest of us to see what you are seeing and maybe to predict what you will do. Think that’s not in the works? Think of all those popup adds on your computer based on what you were searching.
When we can see the future with some certainty, we benefit, don’t we? Pilots of both planes and ships want to know the currents of air and water that facilitate or slow their vessels. Jet stream predictions allow people to err on the side of caution, such as those under storm watches. In January, 2019, AMTRAK cancelled trains to the Northeast while a predicted storm still lay over the American West. And in volcanic lands, people want to know when to flee. Of course, there’s always the danger of “crying wolf.” Shortly after the predicted first eruption of Soufriere Hills volcano of Montserrat didn’t occur, people returned and ignored the ensuing warnings. Nine people died by not heading the prediction.
It’s all about knowing the future, isn’t it? And knowing the future is about security, personal security. Trouble is, we can’t know for certain. We can err on the side of caution, but that’s the best we can do. The unseen jet stream can change directions because of some other unseen phenomenon. Magma chambers don’t always respond as we predict. Earthquakes occur when we least expect them. And humans don’t always act in a predictable manner, regardless of what we interpret in their brains or even from their recent behavior.
How much of your day is spent in anticipating, in knowing the unseen? Aren’t all of your decision-making neurons focused on what is to come both long-term and short-term?
