Objective C Escape Quotes

Kindness consents very readily to the removal of its object – we have all met people whose kindness to animals is constantly leading them to kill animals lest they should suffer. Kindness, merely as such, cares not whether its object becomes good or bad, provided only that it escapes suffering.

There's no real objection to escapism, in the right places... We all want to escape occasionally. But science fiction is often very far from escapism, in fact you might say that science fiction is escape into reality... It's a fiction which does concern itself with real issues: the origin of man; our future. In fact I can't think of any form of literature which is more concerned with real issues, reality.

We’re particularly anxious to get our hands on Pioneer 10—the first man-made object to escape from the Solar System.

There is kindness in Love: but Love and kindness are not coterminous, and when kindness (in the sense given above) is separated from the other elements of Love, it involves a certain fundamental indifference to its object, and even something like contempt of it. Kindness consents very readily to the removal of its object — we have all met people whose kindness to animals is constantly leading them to kill animals lest they should suffer. Kindness, merely as such, cares not whether its object becomes good or bad, provided only that it escapes suffering. As Scripture points out, it is bastards who are spoiled: the legitimate sons, who are to carry on the family tradition, are punished.^ It is for people whom we care nothing about that we demand happiness on any terms : with our friends? our lovers, our children, we are exacting and would rather see them suffer much than be happy in contemptible and estranging modes. If God is Love, He is, by definition, something more than mere kindness.

Jesus asks parents to make yet another choice. Are we raising our children to be safe or to be brave? Are we raising our children to be smart or to be loving? Are we raising them to be successful or significant? How does God raise his children? In his book The Problem of Pain, C. S. Lewis made an observation that is worth lingering over. “Love,” Lewis wrote, “is something more stern and splendid than mere kindness. . . . Kindness merely as such cares not whether its object becomes good or bad, provided only that it escapes suffering.” My vulnerabilities as a parent are such that sometimes I simply want my kids to escape suffering. But if I keep them completely safe, they will never have a chance to be truly good or brave. Is that what I want?

NOTHING CAN GO FASTER THAN LIGHT Of course the idea that there is an ultimate speed limit seems absurd. While the speed of light is very high by earthly standards, the magnitude is not the point; any kind of speed limit in nature doesn't make sense. Suppose, for example, that a spaceship is traveling at almost the speed of light. Why can't you fire the engine again and make it go faster-or if necessary, build another ship with a more powerful engine? Or if a proton is whirling around in a cyclotron at close to the speed of light, why can't you give it additional energy boosts and make it go faster? Intuitive explanation. When we think of the spaceship and the proton as made of fields, not as solid objects, the idea is no longer ridiculous. Fields can't move infinitely fast. Changes in a field propagate in a "laborious" manner, with a change in intensity at one point causing a change at nearby points, in accordance with the field equations. Consider the wave created when you drop a stone in water: The stone generates a disturbance that moves outward as the water level at one point affects the level at another point, and there is nothing we can do to speed it up. Or consider a sound wave traveling through air: The disturbance in air pressure propagates as the pressure at one point affects the pressure at an adjacent point, and we can't do anything to speed it up. In both cases the speed of travel is determined by properties of the transmitting medium- air and water, and there are mathematical equations that describe those properties. Fields are also described by mathematical equations, based on the properties of space. It is the constant c in those equations that determines the maximum speed of propagation. If the field has mass, there is also a mass term that slows down the propagation speed further. Since everything is made of fields - including protons and rocketships - it is clear that nothing can go faster than light. As Frank Wilczek wrote, One of the most basic results of special relativity, that the speed of light is a limiting velocity for the propagation of any physical influence, makes the field concept almost inevitable. - F. Wilczek ("The persistence of Ether", p. 11, Physics Today, Jan. 1999) David Bodanis tried to make this point in the following way: Light will always be a quick leapfrogging of electricity out from magnetism, and then of magnetism leaping out from electricity, all swiftly shooting away from anything trying to catch up to it. That's why it's speed can be an upper limit - D. Bodanis However, Bodanis only told part of the story. It is only when we recognize that everything, not just light, is made of fields that we can conclude that there is a universal speed limit.

MASS INCREASES The final paradox of relativity is the increase in mass due to motion. Mass increase has been observed experimentally in particle accelerators, with increases as great as 3000% for particles traveling at over 99.9% the speed of light. How can the mass of an object get bigger just because it's moving? Intuitive explanation. As we saw in Chapter 2, mass means inertia - i.e., resistance to acceleration. If you push something and it doesn't respond much, then by definition it has a large mass or inertia. Now we just saw that pushing on something that is traveling at close to the speed of light has little effect on its speed because the underlying fields are already moving almost as fast as they can. Thus its resistance to acceleration has become greater and this means its mass has increased. Mass increase is just another way of saying that fields can't propagate faster than c.

The German bombers kept coming. In town after town, Jean-Luc Leclerc could hear the air-raid sirens. But he refused to stop, refused to take shelter. He had one mission, and that was to reach Le Chambon, no matter what it took. He desperately wanted to hug his daughter Lilly, only six years old, and her sister, Madeline, not quite four. He wanted to hold them and never let them go. Even more he wanted to hold his beloved Claire. Surely she had heard about the German invasion. She was constantly listening to the news from Paris and London on the radio. He couldn’t imagine the anxiety she was going through. Finally, just after two in the morning, he reached his objective.

I don’t think of that as a positive, Uncle,” Jacob said softly. “Well, I do,” Avi replied. “In intelligence work, that can come in very handy.” For the next half hour, they discussed the nature of the underground resistance movement that was growing in Germany, its goals and objectives and the risks of joining. Avi mentioned no specific names or places or operations. He spoke in generalities but made it clear to Jacob that this very conversation—the same he’d had with dozens of men, and a few women, throughout the country—was punishable by hanging or by a firing squad.
