Against Gravity

The heart works against gravity.

What do the numbers on the x and y axes refer to? Potential energy is always calculated from a reference point, in this case, height above sea level.

If students struggle to calculate potential energy, illustrate with sample calculations. The final part of the activity, which involves drawing a graph of potential energy, is highly conceptual. The x -axis scale is reversed from the elevation graph because the boys are tramping back down the trail to sea level. Specific data points will simplify the drawing, for example, ask the students to plot the calculated potential energy values for Henry at each hut and at the bottom.

From these few points, they should be able to see that the shape of the graph is roughly mirroring the shape of the elevation graph on the previous page. Extension activities could include discussing the question of gradients steepness of the climb.

What is a negative gradient and where do you find one on the graph? How would you measure the gradient on the mountain? What do gradients have to do with the distance between contour lines on a map? There is a difference in elevation of 20 m between any two contour lines. The closer the contour lines, the steeper the gradient. Ask the students to think about what happens when people climb mountains. What does it feel like when climbing?

Where do the trampers get their energy? Which of the three boys in the activity will require most energy? As they study the elevation graph, get them to discuss where the trampers will have to expend most energy. How will the terrain change as they climb higher?

How might the weather, especially wind chill, affect their climb? This activity focuses on work the change in potential energy. Help the students to link the ideas of force, acceleration, mass, and energy. This acceleration gives us weight, where the force of our weight in newtons is equal to 10 metres per second squared times our mass in kilograms.

Henry has climbed m. His total mass with a pack on is 66 kg. All three boys climbed the same amount, and Rua [with his pack] lifted the greatest mass. Rua lifted a total of 94 kg: Without their packs, Henry, Rua, and Mukasa have a total weight of kg. Henry gets the greatest boost when he is losing potential energy the fastest, in other words, on the steepest descent on the track below Haumata Hut.

This is the story about Kendrick, a man who was kidnapped during America's collapse in the 's, and was used as a labrat in military scientific experiments.

Now he's a fugitive with rouge nanite implants that are slowly killing him, with a kind of intelligence beyond normal understanding.

Other survivors think there's a way to keep themselves alive. It has to do with The Archimedes, a station in space with AI meant to figure out the deepest secrets of the universe, and in essence find God. Th This is the story about Kendrick, a man who was kidnapped during America's collapse in the 's, and was used as a labrat in military scientific experiments. This intelligence calls itself The Bright. What they've learned about the universe could change all of humanity and all of time Before this book, I'd never read anything by Gary Gibson.

He's pretty big in SF but I have to say I wasn't impressed. The writing style was amatuerish and overdone, the characters hard to connect with, and even Kendrick comes across as petulant. The plot has a surreal, feverish quality that makes the whole experience like a bad dream. Half the time I didn't know what motivated these people or why a plot obstacle was such a big deal. It left the whole rest of the book meaningless.

I will say one thing for Gison, though; I was compelled to read on. Something about the way he crafted the story and wove his mystery made me want to figure out what was happening. I kept thinking about it. I believe the best part of the story was the flashbacks to Kendrick's time being experimented on. After that, the story lost much of its oomph.

In the end, I wasn't mad I'd read the story, I was just glad it was over. Aug 03, Kristian Lindqvist rated it it was ok. I bought Gary Gibson's novel at the same time as Neal Asher's because there was something similar about the good looking covers, and I was desperately seeking something hard to bite, akin to Iain M. Banks or Alastair Reynolds. Well, Against Gravity begins okay as a suspenseful cyberpunk thriller, but too soon the plot is revealed from the viewpoint of other actors in the "big game", which is a shame since this story would have worked better if it had been from the perspective of the protagonist I bought Gary Gibson's novel at the same time as Neal Asher's because there was something similar about the good looking covers, and I was desperately seeking something hard to bite, akin to Iain M.

Well, Against Gravity begins okay as a suspenseful cyberpunk thriller, but too soon the plot is revealed from the viewpoint of other actors in the "big game", which is a shame since this story would have worked better if it had been from the perspective of the protagonist Kendrick all the time. Some nice ideas and pulpy B-science fiction fun but ultimately six months later I don't remember anything of this novel when I'm writing this short review now Still, worth checking out, and I'm going to try the "Shoal" series next.

Sep 20, Adrian Leaf rated it really liked it. A near future, post cyberpunk nanopunk dystopian thriller. It is generally considered to be Gary Gibson's weakest novel. I really enjoyed it however, I actually thought it was one of his best. It deals with The Omega Point Theory head on and has a very morally ambiguous slant. The characters are pretty well drawn too, far better than in some of Gibson's other work. Quite a lot to chew on, highly recommended.

I enjoyed this book so much I read it over 2 days.

The story follows a character who was used as an "medical experiment" for nano bots.. Aug 28, Andreea Pausan rated it really liked it.

Those who do not not their history are doomed to repeat it. This book reminded me of the atrocities of WWII, when thousands of people were marched into extermination camps and experimented upon. The story happens in a not so distant future, when US is ruled by President Wilson, under martial law. Due to the terrorist threat real of used as an excuse , thousands of people are locked in a vast subterranean complex called the Maze.

There they are tortured, killed or transformed: Then they must kill each other in a sick game. But the implantation has unexpected results: Years later, after everything is exposed and the Labrats are released, their implants go rogue and start killing them. The answer seems to be back in the Maze. Kendrick is a normal person, a journalist who happened to be in the wrong place at the wrong time and got thrown into the Maze. When his implants go rogue, he does everything he can to survive.

Even if in order to do that, he must go back to hell and face his demons. He is constantly under terrible pressure, threatened, hit, abused over and over, pursued by multiple enemies, afraid and sick and, above all, relentless. He never gives up, despite everything.

What I found most terrifying about this book is its realistic claustrophobic atmosphere, the feeling that this could happen anytime, to any of us. Apr 24, Scifimoth rated it it was ok Shelves: As a general rule I do not like books where the main character has a low level of agency - where they are subject the winds of fortune around them with very little impact. In my view this book suffered from this failing, so I do not like it anywhere near as much as the others from the author.

I lost track of the number of times the main character was kidnapped or taken at gunpoint against his will - probably over 7 times. I did finish it though. It finishes rather abruptly.

Jun 18, Penny rated it it was ok Shelves: This thing was preposterous. Apr 16, Terry added it Shelves: Gary Gibson gets it. In today's mass-produced publishing blitz that stresses profit over quality the authors who actually have some writing ability stand out from the norm. Gibson is one of those.
