If a baby was captured and raised by the monkeys in forest, she won't be able to analyze better than an high school student in a small city, however with trainings, the later mind is reasoning much better than a network of 1000 computers.

The ordinary people always wanted beautiful things being around but only a few men had liked to carry their ugly spirits all along with their lives.

Why many governments don't help all children to use the memory aid of computers and the analytical mind of people from the class rooms, after governments require them to take the memory improvement class, the longer practices will yield the better solutions in future.


DR Albert Einstein did not have a Ph.D. in math, but time and a sense of humor to write the greatest theories and accomplish many genius works? Therefore, when he got older, the Unify Theory was not found after his energy diminished with joyces and loves, behind the secret world of the atomic bomb.

They said Albert Einstein was a slow learner, retarded, and uneducabled; however, Dr Eistein and Vietnamese students had and have this: Life is about 20% in what happens to us and 80% in the way we respond to the events.

When Mr Can Le took the Engineering Mechanics-Dynamics class at UTA on Junior level, he asked a senior Mechanical Enngineering student what is the hardest course in M.E., one said: Thermodynamics II! So he had a Fortran program to calculate 2 new rules in Thermodynamics beside Boyle, Charles, and Gay-Lussac's laws.

You can also check the 2 new rules from: Rare Math for details.

At this time, your math work online is not recorded in memory for printing as in MessageBoard, except 1 line for reprint your formulae which the next user can't see your secret formula, but these softwares can be customized for your company or school works, with a small support. If you can not check a hidden wireless modem in your computer, you won't be able to detect the intruders who enter your machine; therefore this home page can possibly printout the server number of the user who is connecting to your machine, as you are seeing the array of members on the common chat lines, or you can check a machine number of your server for yourself, from my new chat line to discuss a subject from home page or email and text at the Meeting !! :-) ////(^_^)\\\ [*_*](-: !!

~ Love ~ Admire and share between friends or relatives about different resources, beliefs, interests, knowledges, humors, sorrows, and respects. Lovers repeatedly desire each other wonderful feelings and future comforts; they will remember their happy moments as well as pains with traditions. Love will ever last until their good things underscore their powers of the inner selves, or only one death on earth will eventually separate them.

Parents don't have sex with their children but their loves last forever.
Husbands and wives have had sex but about 50% of them are divorced.
Why sexuality created possession for divorces?
Why the teenage couples were rushed to have baby and marriage then get 50% divorced rate?
May be, because 50% of the divorced couples could not handle their loves and health.


~ Beliefs ~ The world first Republic Government had Neron who burned Rome for the entertainment of a king, from his limited bureaucrat and narrow view of feelings. While the major jews in Jerusalem voted to crucify an innocent Jesus Christ from the lack of informations. Thank to all the internet and media people, U.S. First Amendment, Freedom of Information Act, Bell Labs of Tyco Electronics, and those who make communications work!
I am a Christian and I believe that we have the other forms of life in outer space,..for more facts of life, please check Beliefs. and:

You already known some incredible or unimaginable things which happened to the world, so if anything is imaginable, there is possible! Bertrand Russell said: "...fools and fanatics are always so certain of Themselves, but wise people so full of doubts.". Please check my secret theories and the facts in Opinion to have more of your doubts!


Dome Homes protect you from hurricane, tornado, twist, storm, fire, dusts, and noises. Californians around Bay Area from San Francisco to San Jose could use the Dome Homes with the floating floor and base, which is briefly named floatdome, as a houseboat, a simplest form from the raft without hull but barrels or drums, to avoid the damages by earthquakes or Tsunami, and to get the lower housing costs!

If you are thinking about the feasibility, please remember that a tank M113 can swim, and a famous Titanic could even dive forever!

If you are living in Louisiana or other areas with the high threat of floods, or think about the giant floods in the next 40 years, as in the documentary movie "Inconvenient Truth", when the polar ices will melt, you can build a small floating dome home in your backyard for a guess house, a tea room, a small party space, and you can sail away at the killing floods! You can even park your floating dome home inside a larger dome which looks like a huge contact lense!

We can use 2 or more solar panels to be arranged around a vertical windshaft of a windmill with a wind deflector above or below the blades to get solar power and wind power at any wind direction. The rectangular solar panels can be easily detached to reinforce another clear plastic V-shaped wind deflector in front of dome home to also be used as a tidal wave deflector for the beach dome homes

For the Californians, if you are worry a large about the earthquakes, please don't forget that you can build the floatdome and put it on the rail or wheels, to be pulled into your larger swimming spool by a winch and sensor, to live with earthquakes! So enjoy the consumer spending to promote a healthy economy!

Snow On The Net

The above photo was taken in the morning snow storm in Texas on March 21, 2010 at about 9AM. No snow was seen on the floor underneath the net.
Do you like to keep your good farm or backyard's vegetables from snow?
You can try to use the poultry netting to cover your orange farm in the winter, snows stay on the net by statics and slide down the net while the 20 gauge galvanized zinc mesh allow the rain to fall through 1 inch hexagon holes. The maximum slope for the snow to slide down and off your trees is 8 inch rise by 10 inch run slope.
You can do a few experiments with snow on different slopes and gauge mesh sizes for best selection based on your local elevation and Snow Water Equivalent factors:

If the former Fisrt Lady Hillary Clinton did not succeed on Universal Healthcare for Americans because the foreign-owned companies had planed to invest the huge amount of insurance money in America beyond the later year 2000 for their profits, when the crude oil price was very cheap in 1999 from the greater number of imported oil. The two big groups in Insurance and oil industries can flexibly change their targets of investments into the Renewable or Alternative Energy for more profits and the Universal Healtcare for Americans. Since the Iraq war will be ended to raise the number of US imported oil after the election year in 2008.

Most Vietnamese American said that the current failing economy of Republic Socialist Vietnam is caused by the Vietnamese Communist Party. While the young Vietnamese Americans had gained many successful stories around the globe for their educations and new experiences, as the numbers of talented Vietnamese Americans are raising. Nobody denied that the economic failure of Vietnamese Communists have had came from the sole communism, since the human resources had been changed for the bigger Vietnamese government from the old regime, and we did not see any peak nor node for those economic cycles in more than 32 years, when the fighters did the conservative managements!

Some communist countries are loosing their collateral properties to the foreign banks since their nationalized businesses have the fail rate about 80% every year. We have about 10% of success rate for the U.S restaurants after their first year in business! However, these 90% unlucky capitalist could file for bankruptcy, not the same way as the big bosses of Enron or Casino who get rich by commissions and bonusses, before the stock holders or gamblers lose their cashes! By the principles, the communists could not win big money, anyway, but they have to hold on their 80% loosing gambles, anytime, because the communists are affraid to close their loosing nationalized businesses every year.

Moreover, the tax money in a free market economic country usually spent on the private contractors then these rich bosses will spend their profits on citizens, while the rich communist cut off their circularting tax money right after the government spent to build their constructions or national projects!

At a certain period of time in the world, we have a fixed amount of currencies beside the other moneytary values. If a portion of this circulating money is not in America, it is certainly hidden somewhere in the other countries!

Many amateur economists had claimed that President Bill Clinton did sign the NAFTA agreement for the US job losses. The above economists did not claim 22 million jobs which were created by the Clinton Administration from the year 1993 to 2000. Since Bill Clinton and Al Gore had used the economic software to grow the US surplus budget, when they signed the NAFTA agreement.

According to the Labor Expansion Program by Can Le in RareMath with copyright number, when US government has 4% more workers at 26% income tax rate, US Government has raised her budget revenue at about $70,247,415,808 dollars.

Many governments said they don't have enough facilities for their universities! What if their first 2 year college students take correspondence schools or Distance Learnings, to save plenty of rooms for the last 2 years college students, to increase productions?

Vietnamese Communist Government is granting each student only one college entry exam per year, to save their successful cost of communist regime! Why not enter college free of exams to save money! America is taking SAT and few other tests for college entrance because American students got the different text books for the same grade. Why the other students could not enter college by just their highest final grade reports ? Who have the successful golds will make their rules!

Dr Albert Einstein did not graduate from High School. If Government restricts the hopeful students entering colleges to please a foreign President, then how many more Einsteins will be lost to the world?!

If government can not raise taxes, she could hire smarter teachers to help the dummy students get smarter grades, or encourage universities to have the open book exams for more graduate students every semesters, so government can get more tax money from the new higher tax brackets.

Some government could have duplicated one serial number for 3 pieces of their 100 dollar bill and take 2 paper money bills to buy the real gold, wait for the gold price to reach the ceiling high then sell gold to make profit and real money for their real Universal Healthcare! What kind of conscience which prohibited US Government to do the same to reduce the oil price and promote the Universal Healthcare?

Hoping that you will vote better in the election year to make US economy stronger, to feed the world better by any good way, with the existing and new High Technologies, beside her experience in human resources, even if you were from Europe or Asia.
