Cynicism is the easiest of all reactions, right? But it's also so disappointing and self-defeating.

The best simulator for spacewalking is underwater - it allows full visuals and body movement in 3D. Virtual reality is good, too, and has some advantages, like full Station simulation, not just part. Like all simulators, they have parts that are wrong and misleading: an important thing to remember when preparing for reality.
Interpretation
Training for spacewalking can be effectively done underwater and with virtual reality, but one must be aware of the limitations of these simulations.
Chris Hadfield emphasizes the importance of realistic training for astronauts, particularly for spacewalking, which can be best achieved through underwater simulations. He notes the advantages of virtual reality in providing comprehensive simulations but warns that both methods have their drawbacks. Understanding these limitations is essential for effective preparation for actual space missions.

Cynicism is the easiest of all reactions, right? But it's also so disappointing and self-defeating.
Spacewalking trumps everything. Viscerally, it is a phenomenal place to be; to be able to glance right and see the world, glance left and see the universe, and realise for a moment that you're holding on to your known existence with one hand. That's the thing.
The Nile, draining out into the Mediterranean. The bright lights of Cairo announce the opening of the north-flowing river’s delta, with Jerusalem’s answering high beams to the northeast. This 4,258 mile braid of human life, first navigated end-to-end in 2004, is visible in a single glance from space.
The world, when you look at it, it just can't be random. I mean, it's so different than the vast emptiness that is everything else, and even all the other planets we've seen, at least in our solar system, none of them even remotely resemble the precious life-giving nature of our own planet.
Life off Earth is in two important respects not at all unworldly: you can choose to focus on the surprises and pleasures, or the frustrations. And you can choose to appreciate the smallest scraps of experience, the everyday moments, or to value only the grandest, most stirring ones.
Our role is to develop techniques that allow us to provide emergency life-saving procedures to injured patients in an extreme, remote environment without the presence of a physician.
We've learned that musical ability is actually not one ability but a set of abilities, a dozen or more. Through brain damage, you can lose one component and not necessarily lose the others. You can lose rhythm and retain pitch, for example, that kind of thing.
There's no such thing as saying that we'll ever find the ultimate cause of stuff. We can only work to push our understanding one step further.
The 'medical examination' to which abductees are said to be subjected, often accompanied by sadistic sexual manipulation, is reminiscient of the medieval tales of encounters with demons. It makes no sense in a sophisticated or technical framework: any intelligent being equipped with the scientific marvels that UFOs possess would be in a position to achieve any of these alleged scientific objectives in a shorter time and with fewer risks.
The dramatic importance of climate changes to the world’s future has been dangerously underestimated by many, often because we have been lulled by modern technology into thinking we have conquered nature. This well-written book points out in clear language that the climatic threat could be as awesome as any we might face, and that massive world-wide actions to hedge against that threat deserve immediate consideration.
If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.
I am a futurist, projecting trends in science into the next decades and century, but ironically my two daughters - one is a neuroscientist and the other is a pastry chef - tell me that my taste in music is positively prehistoric.
