Science is not about making predictions or performing experiments. Science is about explaining.
A mathematician is an individual who believes that prophesying that his dog will die if he deprives it of food constitutes a prediction.
Although our eyes can not penetrate the darkness of the future, scientific geopolitical analysis enables us to make certain predictions.
When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible. Nevertheless, no one doubts that we are confronted with a causal connection whose causal components are in the main known to us. Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.
Here’s my prediction: Ninety percent of what everyone will drink will be red wine, and one of the biggest markets will be China.
I don't read, much less follow, the valuations or predictions. I study the numbers.
Hope is not a prediction of the future, it's a declaration of what is possible.
Wouldn't you like to contribute to an event that is part of Christ's own prediction, "I will build my church"?
Social Security has been effective for 70 years; prior predictions of its demise have been totally overstated.
I have seen some astrologers who predicted wonderful things; but I have no reason to believe they predicted them only from the stars, or anything of the sort. In many cases it is simply mind-reading. Sometimes wonderful predictions are made, but in many cases it is arrant trash.
We would never get away from it. ... It's bad enough as it is, but with the wireless telephone one could be called up at the opera, in church, in our beds. Where could one be free from interruption?
Men might as well project a voyage to the Moon as attempt to employ steam navigation against the stormy North Atlantic Ocean.
Only human beings can look directly at something, have all the information they need to make an accurate prediction, perhaps even momentarily make the accurate prediction, and then say that it isn't so.
People ask me what my predictions are for publishing and how digital is changing things and I tell them my only real prediction is that is it's all changing. Amazon, Google and all of those things probably aren't the enemy. The enemy right now is simply refusing to understand that the world is changing.
The choice, as Wells once said, is the Universe-or nothing. . . . The challenge of the great spaces between the worlds is a stupendous one; but if we fail to meet it, the story of our race will be drawing to its close. Humanity will have turned its back upon the still untrodden heights and will be descending again the long slope that stretches, across a thousand million years of time, down to the shores of the primeval sea.
The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.
The time will come when man will know even what is going on in the other planets and perhaps be able to visit them.
No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.
Some think that solar work is pretty well played out. In reality, it is only beginning.
The distance between the earth and her satellite is a mere trifle, and undeserving of serious consideration. I am convinced that before twenty years are over one-half of our earth will have paid a visit to the moon.
Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
From the moment they had left the Earth, their own weight, and that of the Projectile and the objects therein contained, had been undergoing a progressive diminution. . . . Of course, it is quite clear, that this decrease could not be indicated by an ordinary scales, as the weight to balance the object would have lost precisely as much as the object itself. But a spring balance, for instance, in which the tension of the coil is independent of attraction, would have readily given the exact equivalent of the loss.
They have likewise discovered two lesser stars, or satellites, which revolve around Mars, whereof the innermost is distant from the center of the primary exactly three of his diameters, and the outermost five: the former revolves in the space of ten hours, and the latter in twenty-one and a half, so that the squares of their periodical times are very near in the same proportion with the cubes of their distances from the center of Mars; which evidently shows them to be governed by the same Law of Gravitation that influences the other heavenly bodies.
Our sun enlightens the planets that belong to him; why may not every fixed star also have planets to which they give light?
The shape of the heaven is of necessity spherical; for that is the shape most appropriate to its substance and also by nature primary.
