Two colors that produce white when added together are called complementary. The color complementary to a primary color is called a secondary color. The complementary or secondary colors for red, green and blue are cyan, magenta and yellow respectively. These three colors are often referred to as the subtractive primary colors. When the three are combined in subtractive color mixing, they produce black.

- Similarity between music and language
Every human in culture we know the music and language, these are universe, genuine human universe when they go way back in our specie’s history. So the question what these two things might have been common has occurred a lot of people when it’s two of them both involve complex sequences that afford in time both forms in communication, it’s interesting, philosophers since Plato going back over 2000 years, scientists including Darwin who wrote about possible evolutionary links between music and language in his book “The Descent of Man”, an artist including Leonard Bernstein who gave a set of lectures Harvard in the 70s about possible connections between the grammar of music and the grammar of language according to Noam Chamsky theories.
So it’s a persist question and I think it continuously at from scientists today, because they are just in basic obvious similarities. For example, both music and language have rhythm by which I mean systematic patterns of timing, accent and grouping. They both have melody, meaning structure patterns of pitch over time. And they both have syntax, mean … elements like notes, words and principles where combining those elements of sequence sentences are just random sequences verbs, music is nowadays compositions of far from random sequences of notes, their principles. And they both convey emotion or affect using sound, you can tell somebody’s emotions … their voices, you can get a lot of emotional information about music is conveying happiness, sadness or mixed emotions …happy.

- Faults and Earthquake
The dislocation of the rock occurs from the earth’s surface seven kilometers to several hundred kilometers vertically down to the crust. It refers to the epicenter which located vertically to the focus or hypocenter, and the energy releases and transfers through epicenter. It will result in a seismic wave which decreased as it moved away from the epicenter.
The location below the earth’s crust where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter Faults are fractures in the earth’s crust. By using fault maps, we could identify the location of the earthquake.

- Are we animals?
Far too many people, hmmm….often say things like animals do this but we don’t, or else
this animal does this and that animal does this, but the humans don’t do things like that. Those statements have some hidden assumption that we are not animals. When we say animals do this animals do that, we often assume that we’re not animals. If we are not animals, what are we? Are we plants or trees or flowers? No, we are not. Then okay, we are not plants, are we microorganisms, really tiny microscopic things? No, we are not. Then the natural conclusion must be we are not living things. That’s not true. Yes, we are animals and I see animals in us and I see humans in animals. So, I’m going to talk about the animal behavior and human nature. In order to understand human nature, we can look into animals’ eyes and animal behavior and find something about what made us who we are.
68 Water challenge
Today I want to talk about water, and the…the law that surrounds drinking water, to talk about its quality, talk about what your rights are to clean water, to also give you a sense of what key threats are to drinking water, what your exposure might be, and what we might do about it, both legally but also personally.
Water is a critical component of our environment and our bodies, your body is close to 70% water. You can go for several weeks two to three on average without food, you can only go for about four minutes without air, and you can go for maybe four or five days without water before you die. So water is absolutely critical, and one of the key arguments I want to make today is that it’s a largely neglected area of environmental law, given the rapid increase in our knowledge about chemical threats to water quality, and where those threats come from.
69 Big Bang Theory
The lecture is about dark energy. Dark energy Is an unknown form of energy, which is hypothesized to permeate all of space and accelerate universal expansion. Dark energy constitutes most of the total energy in the observable universe though its density is low. Two proposed forms of dark energy are cosmological constant and inconstant scalar fields. A field that is similar to dark energy and could inflate early universe is called the big bang.
The lecture is about the Big Bang Theory which is a cosmological model for the universe. The detailed measurements regarding the expansion are at around 13.7 billion years ago, which is far before then the first estimation of about 10 – 20 billion years. The newest found star is roughly 30 billion years old, and thus it can be matched with the current prediction regarding the expansion.
Our universe was in a hot dense state, then about 1.4 billion years ago, the expansion started. People usually think Big Bang happened 10-20 billion years ago but study indicated that it actually happened x billion years ago. The universe is a little older than the oldest stars, the observation is perfectly matched with the big bang theory. However, we still don’t know how the big bang happened.
70 Prevention of epidemic transmitting
In the developed world, like the United States, it uses various methods to prevent epidemic transmission with a wide range of resources such as the invention of antiviral drugs and vaccines and health management.

Hence, it is the significant challenge in the future.
71 History of Epigenetic
Now I like the history and one thing I want to go over briefly is a history of epigenetic research and this is from my perspective now. I got into this field in the early 90s. and what I have here is plotted publications total publications and function of time here. and on a linear graph. so what I did for this is I wanted to show that basically up untill around the year 2000. There’s an inflection point right around two thousand five right in here where it looks like basically nothing really is happening much in the field of epigenetics. To the point where it’s actually going vertical and a lot is happening in field of epigenetics. Now if you plot this rather than on linear paper semi-log paper. what you will find is that what I’m showing is an exponential growth curve for publications in the field of epigenetics. and that in the scientific community. There’s a doubling of the epigenetics papers every one and a half to two years. Last year alone we put into publication summers between fifteen and twenty thousand papers which took us 15 years from 1992 to 2005.
72 Flower temperature
Why the bumble bees pick some flowers over others? Researchers have known for a while that flower’s color can be a signal. Color in short hand that says to a bee: hey, I get some good quality nectar here, want to stop by for a visit. But new findings show that bees also use color to get clues about a flower’s temperature. And according to a study from a British research team published in the journal Nature, some like it hot. Bees use up a lot of energy just stay in warm on some days. In fact, they can’t even fly if they are too cold. So if one flower is warmer than another, a bee can save some of its fuel by basking on that flower while it’s doing its pollinating business. And it turns out that bumble bees consistently do choose warmer flowers over cooler ones, even when the two flowers offer up the same quantity and quality of nectar. Some plants seem to be evolutionarily adapted to be slightly warmer because the warmer ones get visited more by the chilly bees. When it comes to getting pollinated, apparently the heat is on, and that is the buzz.
73 Energy consumption
This is a 40-watt light bulb. If you leave it on all the time, it uses one kilowatt every day. And it’s possible to express all forms of power consumption using this unit of the light bulb. I started measuring everything around my house, around my office. And I found some surprising things. First, I plug in a phone charger. And it didn’t even register on this power meter. It uses one hundredth of a light bulb of power. So I don’t think the phone chargers can be our NO.1 phone energy consumption. Just taking one hot bath everyday uses the same energy, same power of five light bulbs on all the time, non-stop. And I found I’ve been steadily using 40 light bulbs worth of gas for heating, making hot air or hot water. And that surprises me. Transport is one of the biggest forms of energy consumption, and it uses about a third about our energy. If you drive an average car 50 kilometers a day, that corresponds to adding 40 light bulbs on all the time. Today, the average British person is using 125 light bulbs of power. That’s 125 light bulbs on all the time, non-stop. That’s huge.
The good thing is people began to be aware of the problem and have taken some actions. It declines, documents are the only evidence, it occurs in various species, it results in huge loss and maybe will have catastrophe, the positive thing is people began to be aware of it and are taking actions to fix it. Those conclusions are real and well documented, and they declined. Conclusions have been supported by strong evidence, which is the only one. The drivers contributed to the decline are varied depending on the species There is a possibility of a huge loss, but the positive thing is that people began to be aware of this and take some actions to fix the problems
- Smart Consumer
The consumers are smart, consumer values are important for business. They are smart in choosing the product, brand image; it is essential for the business to create value. An advertisement regarding the softest product which is also strong can fulfill demands of the smart consumer. Majority of people are using only a few seconds to decide whether to buy. This is fundamental engineering contradict. You don’t want it to be separated when you put it in the washing machine.
- Market economy
The market economy appeared in developed countries. It was documented, and scientific evidence supported it. The worker classes emerged in the 19th and 20th centuries. The market economy decreases the worker’s living standards and life expectancy, so the regulation was released to protect the benefits, and the working environment condition is far better than that 100 years ago.

- Global warming
The constant presence of greenhouse gases drains into the atmosphere is harmful. Can we take risks to ignoring the prediction of global climate change? After 11 years of continuous global warming, climate change takes place on the worldwide scale.
- New energy
There should be no reasonable denial regarding the climate change as its effects were becoming apparent. Even though population bomb hypothesis, which population would outpace agriculture production, did not become a reality, we should not ignore the convincing scientific evidence of the changing climate.
- Face recognition
How can people recognize human faces? This is a hard but brilliant question. People should appreciate something. People can get visual information from faces and put a name on it. We can tell one’s identity, age, work, health condition, politics, and friends. Recognizing faces is amazing, difficult and a clever thing. In conclusion, people can get a lot out of faces.
