Don't all of us have only "opinions"?
Rather arrogant of anyone to deny any god rather than merely doubt it, based on their experiences. Especially when their god mostly screws people who are disbelievers: But they don't say anything about doubters. Besides, they sing of their wretchedness, so how bad can a doubter be?

In order to lower the worlds population growth, what would be the ideal way to do this?

I've been thinking of biological means, such as spreading infectuous bacteria like smallpox or plague in city centers or in waters near cities. The problem however, is that the bacte.ria are not easily accessible

Are there any chemical or biological means to be used as potent mediums in narrowing the numbers of humans? Two factors should be prioritized: availability and spread. The fact that the chemicals/bacteria could be easily treated would prevent the narrowing process from getting out of hand.

Some Indian cities, Bangladesh and Lagos would be ideal targets due to their relative lack of medical access and low hygiene. Chinese cities seem to be cleaner and the risk of being caught would also be much higher.

Birth rates have been declining since the 60s. Population is growth is a problem that will largely solve itself.
>>
Should I report this to the police right away?
>>
the best way to lower population growth is time; the only reason there is such a big population growth is that medicine, hygenic practice, education and the cultural revolution caused by growing global access to the internet allow for third-world countries to have much lower infant mortality rates. More people are surviving after being born in impoverished areas, which means that people in said areas do not need to have as many children, and will eventually reach the same average children per household as the West, and population growth will begin to slow down again.

>Bangladesh and Lagos would be ideal targets due to their relative lack of medical access and low hygiene
You seem to be misguided, the life expectancy in Bangladesh has increased dramatically in the past decade

Einstein was a moron and a thief. He stole patents when he worked for the Swiss patent office. His only 'brilliance' was in his ability to PLAGIARIZE and STEAL OTHER PEOPLE'S IDEAS, PASSING THEM OFF AS HIS OWN. Einstein's education, or lack thereof, is an important part of this story. The Encyclopedia Britannica says of Einstein's early education that he "showed little scholastic ability." It also says that at the age of 15, "with poor grades in history, geography, and languages, he left school with no diploma." Einstein himself wrote in a school paper of his "lack of imagination and practical ability." In 1895, Einstein failed a simple entrance exam to an engineering school in Zurich.

This exam consisted mainly of mathematical problems, and Einstein showed himself to be mathematically inept in this exam. He then entered a lesser school hoping to use it as a stepping stone to the engineering school he could not get into, but after graduating in 1900, he still could not get a position at the engineering school!

Unable to go to the school as he had wanted, he got a job (with the help of a friend) at the patent office in Bern. He was to be a technical expert third class, which meant that he was too incompetent for a higher qualified position. Even after publishing his so-called ground-breaking papers of 1905 and after working in the patent office for six years, he was only elevated to a second class standing. Remember, the work he was doing at the patent office, for which he was only rated third class, was not quantum mechanics or theoretical physics, but was reviewing technical documents for patents of every day things; yet he was barely qualified.

He would work at the patent office until 1909, all the while continuously trying to get a position at a university, but without success. All of these facts are true, but now begins the myth.

(cont)

Supposedly, while working a full time job, without the aid of university colleagues, a staff of graduate students, a laboratory, or any of the things normally associated with an academic setting, Einstein in his spare time wrote four ground-breaking essays in the field of theoretical physics and quantum mechanics that were published in 1905.

Many people have recognized the impossibility of such a feat, including Einstein himself, and therefore Einstein has led people to believe that many of these ideas came to him in his sleep, out of the blue, because indeed that is the only logical explanation of how an admittedly inept moron could have written such documents at the age of 26 without any real education.

HOWEVER, THE TRUTH IS: HE STOLE THE IDEAS AND PLAGIARIZED THE PAPERS.

Therefore, we will look at each of these ideas and discover the source of each. It should be remembered that these ideas are presented by Einstein's worshipers as totally new and completely different, each of which would change the landscape of science. These four papers dealt with the following four ideas, respectively:

1) The foundation of the photon theory of light;

2) The equivalence of energy and mass;

3) The explanation of Brownian motion in liquids;

4) The special theory of relativity.

Let us look at the last of these theories, the theory of relativity. This is perhaps the most famous idea falsely attributed to Einstein. Specifically, this 1905 paper dealt with what Einstein called the Special Theory of Relativity (the General Theory would come in 1915).
This theory contradicted the traditional Newtonian mechanics and was based upon two premises:

1) in the absence of acceleration, the laws of nature are the same for all observers; and
>>
>>8713840
(cont)

2) since the speed of light is independent of the motion of its source, then the time interval between two events is longer for an observer in whose frame of reference the events occur at different places than for an observer in whose frame of reference the events occur in the same place. This is basically the idea that time passes more slowly as one's velocity approaches the speed of light, relative to slower velocities where time would pass faster. This theory has been validated by modern experiments and is the basis for modern physics. But these two premises are far from being originally Einstein's. FIRST OF ALL, THE IDEA THAT THE SPEED OF LIGHT WAS A CONSTANT AND WAS INDEPENDENT OF THE MOTION OF ITS SOURCE WAS NOT EINSTEIN'S AT ALL, BUT WAS PROPOSED BY THE SCOTTISH SCIENTIST JAMES MAXWELL in 1878.

Maxwell studied the phenomenon of light extensively and first proposed that it was electromagnetic in nature. James Maxwell wrote an article to this effect for the 1878 edition of the Encyclopedia Britannica. His ideas prompted much debate, and by 1887, as a result of his work and the ensuing debate, the scientific community, particularly Lorentz, Michelson, and Morley reached the conclusion that the velocity of light was independent of the velocity of the observer.

Thus, this piece of the Special Theory of Relativity was known 27 years before Einstein wrote his paper. This debate over the nature of light also led Michelson and Morley to conduct an important experiment, the results of which could not be explained by Newtonian mechanics. They observed a phenomenon caused by relativity but they did not understand relativity. They had attempted to detect the motion of the earth through ether, which was a medium thought to be necessary for the propagation of light.

OP being a mathematician is about learning how to solve problems people and computers don't know how to do yet.

We develop the mathematical tools for the other scientists to use. I'm working right now on better ways of modeling historical tsunamis to give bounds on tsunami risk for costal areas.

After your first year or so, your classes will focus on how you know a thing is true or how to use something you know to solve a problem you don't know the answer to yet.

The most likely explanation to the Fermi paradox is that the speed of light is hard limit on traveling matter. That combined with the fact that intelligent might not equate to the ability to travel in space or transmit messages to us. Maybe dolphins evolved on another planet that are extremely smart, but they have no arms and must live in water.

This applies to me. I'm very gifted but have ADHD, OCD and anxiety disorder. I usually underachieve on any standardized test, despite being very capable. I have to receive accommodations.

I am very good at abstract thinking, but have low processing speed (I'm deep but slow). I get distracted easily and can hardly ever focus.

I can spend 8-10+ hours studying math/cs without a problem though. I impress my professors quite a bit with my gifts and other people. People know immediately I am very intelligent and in areas of interest of mine it shows.

My gifts cover my LD and my LD covers my gifts in school. Odd to be gifted and have an LD.

OCD and anxiety aren't learning disorders. They might keep you from learning something, but that's secondary.

The real redpill is to realize that in the nature there are no...

- Negative amounts of stuff ("There were -5 persons in the room")
- Zero amount of something (The room either has no people or has >=1 persons. There can't exist 0 persons because 0 implies nonexistence.)
- Fractions ("There were 3.25 persons in the room")
- Infinity ("There were infinite number of people in the room")

Thus, we should do math strictly with natural numbers. And not only that, but we should forget about the silly concept of "infinity" and just decide that there are no more numbers after Graham's number.

If base-4 is representative of the genetic code of DNA (ACTG) and is constant for producing complex life forms. Then what reason is there in using base-10?

Quaternary numeral system appears to be a more accurate representation of *objective* universal mathematics as opposed to base-10 which is a product of human convention (counting hands).

If evolution is a driving force which led to consciousness then surely there must be some special significance to base-4 beyond DNA?

Our number system is purely historic, good luck convincing others to change it.
Also, binary is king
Your atcg can be broken down
At=0
Ta=1
Cg=1
Gc=0

Therefore atcg is really 01, tacg=11

I probably gave you too much credit though, and you assumed each nucleic acid could be represented in base 4, while you can it's twice as inefficient
