Graph Visual
Imagine a hill when thinking of graph gradients - steepness indicates rapid change.

As we moved from left to right, the graph's gradient showed a steep increase.
Positive vs Negative
Positive gradient goes up to the right, while negative descends to the right.

The line's negative gradient indicates a decrease in values.

amazingly, there is an electrical gradient, head to tail, that's generated that tells the piece where the heads and the tails go and in fact, how many heads or tails you're supposed to have. So what we learned to do is to manipulate this electrical gradient, and the important thing is that we don't apply electricity.

There are strong reasons for believing that space goes on beyond the limits of our observational horizon. There are strong reasons because if you look in opposite directions, conditions are the same to within one part in 100,000. So if we are part of some finite structure then, if the gradient is so shallow, it is likely to go on much further.

Because of its gradient, it is the site of many spectacular waterfalls, like the Unchalli Falls, near which, on a full moon night in winter, you might even glimpse a moonbow - a rainbow generated from the moonlight. This is the river Aghanashini - 'the cleanser of sins.

A lot of our fiscal deficit went to fund consumption and really did not get used to build investment and infrastructure. The trouble is, you can get a spurt in GDP growth, which may not be sustainable. I would much rather build the gradient of a long-term marathon.

Low socioeconomic status carries with it an enormously increased risk of a broad range of diseases, and this gradient cannot be fully explained by factors such as health-care access.

Brexit is a cliff, not a gradient. The mistake we are in danger of making is to believe that some Brexits are better than others when the fundamental problem is Brexit itself.
