The talk, as I remember it, plus some stuff I had to cut for time is below. The jury is still out on the theory, and there are plenty of reasons to doubt it. But if it successfully predicts what happens over the next ten years it will have in good part proved its power.

Is this the way innovation progresses, a never-ending stream of new things? If you look at the history of technological innovation over the course of decades or centuries, not just years, it looks completely different.

It looks like innovation comes in waves: This was followed by the spread of the railways and steam power, the age of steel, and the Age of Oil, Autos, and Mass Production from the beginning of the 20th century to the s. The wave that we are currently in, the Information and Communications Technology Revolution, started around These cycles have eerie similarities.

What dynamic could cause it? From the Industrial Revolutions to the Information Revolution. Her answers lie not just in technological change, but in the social, institutional, and financial aspects of our society itself.

When this system allows a fundamental and basic innovation, the system can cause a technological revolution. For example, here is a group of some of the technologies involved in the start of the Railroad revolution.

The railroad was invented to solve a problem: But the railroad addressed a broader and more basic need: It did more than move coal from mine to ship, it moved goods from city to city, it moved mail from city to city, it moved people from city to city, and those people started living away from their hometowns en masse for the first time.

Another constellation of technologies started the ICT revolution: Some of these together allowed the creation of the microprocessor. Originally built to power portable calculators, it ended up addressing another broad and basic need and started a new technological revolution.

When some of the technologies in a linked system progress faster than others, the laggards become the limiting factor in the system. The system can not progress until the reverse salient is cured, so economic resources are directed to its improvement.

If you see a reverse salient, you have found a problem whose solution is far more valuable than it may first seem. Currently, the most obvious reverse salient is battery technology.

The techno-economic paradigm shows a way of using the new technology to make businesses more efficient and profitable, and so more competitive than existing businesses.

Previous Broadcasts

But existing businesses have a techno-economic paradigm of their own, the one associated with the previous technological revolution, and they have a lot invested in the old way of doing business. So adoption of the new technologies is slow at the beginning and incumbents resist it.

Money starts to flow into the sector. But a few hit big, and other financiers notice. In the current ICT revolution, think about the investments in Apple Computer and Intel by the then new venture capital industry 3.Put on your lab goggles and start learning chemistry with these resources.

Find instructions for chemistry experiments and learn about chemical reactions, elements, and the periodic table in this. We can write it in terms of the (reverse) formation reaction of NO 2 and the formation reaction of N 2 O 4: We must multiply the first reaction by 2 to get the correct overall balanced equation.

We are simply using Hess’s law in combining the Δ H f values of the formation reactions. Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, is an inorganic compound with the formula Na BH white solid, usually encountered as a powder, is a reducing agent that finds application in chemistry, both in the laboratory and on a technical scale.

It has been tested as pretreatment for pulping of wood, but is too costly to be commercialized. My hair is frizz free after paying two hundred dollars to my hair stylist.

I did have to sit through the harsh smell while I wore the mask while the hairstylist was wearing his mask and straightening my hair.

A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical are several different types of chemical reactions and more than one way of classifying them.

Writing a standard formation reaction Write a balanced chemical equation for the standard formation reaction of solid potassium dichromate.

The standard formation reaction of a chemical compound has mole of the compound as its only product, and for reactants has only elements in their standard state%(1).
