Along the automatic telescopic ladder down the cellar, what I saw along the way opened the eyes of the two science babies, the little tyrant, the entire basement is the private property of the little short legs.

"This is the latest LED energy-saving lamp, 200 lumens."

This Fitz could even sigh with energy-saving lamps, and Anna was silent.

"Isn't this Osborne's concept product, an intelligent manipulator that can also recognize commands by voice?"

The concept product is bought for someone like me, Anna said to herself, and he thought Fiz was making a fuss.

"Anna, is it a micro and nano printer in front, hell, I only saw the electromagnetic field confinement technology in 06 years, and now it has been built?"

"Minimum 100nm. However, consumables are expensive, and when the printer is adjusted to the micro and nano level, it consumes needles, and a needle costs thousands of dollars. ”

Typical can afford to use.

Anna was trapped, and if she hadn't had some savings before, she would have been running at a deficit right now.

There are several tables in front of it, and in the middle is a computer desk, where a computer host is placed, the display screen is dragged to four, and four 29-inch large screens are constantly jumping out of codes.

On the left against the wall is a cluster of 256 cores, hundreds of indicators are flashing, liquid nitrogen is cooling, and indoor air conditioning is 24 hours a day.

On the right against the wall is the physical and chemical biology laboratory of the little short legs, and in the middle is a metallurgical microscope.

……

Fitz's eyes are shining, and his eyes are red, this is the favorite of tech nerds!

Simmons was concerned about the rest, and she felt that the basement was so big, even with so much equipment, it still didn't feel crowded.

It's the fifth-highest home price in the U.S., Beacon Hill.

Don't be too arrogant.

In fact, this is Simmons misunderstood, Dr. Killian has a relationship with the Beacon Hill real estate developer, Maya bought it early, there is a discount, when it was purchased, it was only 40 million, and it was paid off in 30 years, which is not too rich.

Anna saw that Fitz was interested in the metallographic microscope, and introduced: "This is what I used to analyze the diameter of the gold wire, and now the picture shown by the metallographic analysis is the electrical circuit of the electric pulse bomb, and the gold wire used, the diameter of each gold wire is 1000 atoms, and I use it to print it into an amplified cascade circuit." ”

Fitz was amazed, Anna had so many inventions, electromagnetic bombs, electric pulse bombs...... And also......

Fitz looked at the gold leaf placed in the alcohol: "Are you making graphene?" ”

Anna explains: "Yes, the gold leaf is a complete sample on top, which I picked out by folding it in half 35 times with tape and am now preparing to try to make graphene capacitors. ”

Fitz: ......

No way, once it comes to infrasonic weapons, it involves output power, the power is too small, and the lethality of infrasonic weapons is insufficient, so Anna has to make large-capacity storage batteries.

The air conditioning in the cellar was turned on slightly lower and it was a bit cold.

Anna asked the three of them to put on their clothes,

Of course, Anna doesn't have enough to do to show off her studio, she's a busy person and doesn't have so much to spare. Turn on the computer and type a few commands to bring up a few hidden files from the Linux system.

"Take a look."

Inside the file are compressed pictures, all old newspaper clips, looking at the date, the time span ranges from 1946 to 1965, more than 30 pictures, the content of the pictures, all of which are the results of the gravitational constant measured by the students in the news report login laboratory.

The opening is sensational adjectives such as shock and world attention, which is quite the style of UC shocking the party.

Dr. Hall was puzzled that he wasn't shocked to feed the old sow on the street.

Anna pointed to the newspaper with her index finger and used her pen to record the data on the newspaper and list them in a table.

Then Dr. Hall looked at it and saw that the clue was that it was the same gravitational constant, but it was a different value.

It is necessary to note here that the gravitational parameters measured by experiments are not constants in themselves.

This has to do with the gradual development of human cognition.

In 1687, Newton published Gravitation in the Principles of Mathematics of Natural Philosophy.

Since then, scientists have gotten ideas from it.

They thought that the weight of the earth could be weighed based on gravitational force.

However, it was not until 71 years after Newton's death, that is, in 1798, that the scientist Cavendisi got a spark from the light offset amplification measurement, and finally combined with the Coulomb torsion meter to design the "torsion scale", which weighed the mass of the earth and calculated the gravitational constant.

Over the next two hundred years, as the understanding of gravitational force deepened, scientists came to realize that the gravitational constant is not a fixed value, that it increases as the universe expands, and that the value itself is biased because measurements cannot eliminate the interference of other gravitational forces.

However, the error of the normally measured data is in the range of one thousandth.

The data written down by Anna, that is, the results of experiments in the 20 years after 1945, the deviation value is at least 1%, and some are very exaggerated, even reaching 10%.

At that time, it caused quite a stir, and a group of ignorant fellows shouted that there was a problem with the Cavendish experiment, how could the gravitational constant change so much, and even pulled Newton's corpse out and whipped it.

There was a lot of uproar.

However, later scientists decided that it was an unrepeatable experiment and put them into the civil science.

"Isn't this a matter that has already been sealed?!" Dr. Hall already had a guess in his mind, but he would have preferred Anna's opinion.

Anna disagreed: "Scientifically, Newton with a coffin was pulled out and beaten several times!" ”

"Look at the test site."

Lawrence Berkeley National Laboratory, University of California, Los Angeles, University of California, San Diego,...... More than a dozen newspapers, 20 years, all in the same place where the problem is going wrong – California.

"What do you mean......" Dr. Hall pondered.

There are no coincidences in science.

"Ph.D., in 1968 Gabriel discovered that Euler's equation can describe strong nuclear forces. After several years of travel, Leonert's research finally led to the formal establishment of string theory in physics. Until then, there was no such thing as a closed-string graviton. ”

Gravitational force is a very strange force, and the other three of the four positions can be included in the unified field theory, but gravity cannot.

Compared with the other three of the four forces, the electromagnetic force, the strong interaction force, the weak interaction force, and the gravitational force are 40 orders of magnitude apart, which is pitifully small.

At that time, scientists pondered why the same force created by God was like a son of a bitch.

Too unsociable.

So string theory experts put forward a concept, gravity is a very special force, the light looks not the same mother, the other forces are open string vibration, and only gravity is closed string transmission.

The open string must be fixed to the space-time membrane of the universe, while the closed string can penetrate the space-time membrane.

It's like the sun's rays, when they shine on the glass, the glass can't feel it, in fact, because most of the light passes through.

The gravitational pull is the same, and humans can't feel it because most of the gravitons (closed strings) pass through.

In another phrase, it was created by the God of God and can penetrate the universe.

"You're saying that if there's a substance that can change glass penetration..."

The rest was self-explanatory, and Dr. Hall stopped talking, taking out a pen and paper and counting.

Anna breathed a sigh of relief and finally dismissed Dr. Hall.
