Stark's only contribution was to ease the relationship between mother and daughter. After the two had a common language, Maya relaxed Anna's supervision.

Now, with Maya turning a blind eye, Anna can use the small underground workshop for the time being.

Dr. Hall gave Anna a list of books, and Anna was immersed in her studies.

Time flies quickly, and in a blink of an eye it is the day of the visit and study, and Anna dresses up and walks out of the campus with the mad teacher in the envy of a group of little children.

The city of Cambridge itself is a model for Cambridgeshire, England, when more than 100 Puritans, who can be said to be socially knowledgeable, crossed the ocean to Boston, in order to allow their children to receive higher education, modeled on Cambridge University, and jointly funded the establishment of Harvard University.

As the representative primary education school in the city of Cambridge, Weston Cambridge School is particularly British in terms of student management, the school uniform is very easy to recognize, shirt with cardigan, pleated skirt with leggings, round toe flat boots.

Children are taught to wear school uniforms on the first day of school.

Anna has always done things with a straight face, the tie is tied in a standard four-hand knot, and the slightest fluff on the cardigan cannot be tolerated.

Of course, she doesn't think it's conformist, in her understanding, first learn to run and then learn to jump, first learn the rules and then learn to innovate in the rules, just like soldering circuits, she can't tolerate the gap between the component pins and the pad more than 4mil.

There is too much hair, it is easy to curl as soon as it grows, and the dense hair forms wavy curls, which looks like Hermione in Harry Potter, the difference is that Hermione has blonde hair, Anna has flaxen curls, and she brushes her hair behind her ears, and Anna is curled in sitting in the school bus.

The representative of the school foundation is Anne Weaver, that is, the dean of S.H.I.E.L.D., Anna doesn't know that she also lives in the small town of Weston, it seems that there is a child, in the ninth grade of the school, Anna and her are old acquaintances, and the road does not seem awkward.

"Anna, I'm an expert in child education, and I have a Ph.D. in psychology from Harvard University." Anne Weaver and Anna's first close chat.

"Wow, so you're the guy who sued Maya." The court asked Maya Hansen to do a psychology career evaluation, and Anne Weaver was the evaluator, and Maya had already appealed and received a court summons at noon, and the certificate was signed by Anne Weaver.

The enemies saw each other very differently.

Anne Weaver handed Anna a bottle of milk powder, three packets of one bottle, soaked into a suspension.

Anna couldn't help but glance up at Dean Weaver, and she felt that Maya deserved it.

Grabbing the bottle and swaying it up and down, the seven-year-old little fart girl who pretended to be tender and sucked the bottle seemed to damage her image, Anna glanced at the side and found that there were four classmates around the big children, no one paid attention to herself, forget it, it doesn't matter if you suck in the car.

Ducks run throughout Boston, and even the Boston Museum of Science, which has a Boston duck starting point right in front of it.

The hand-painted book gives way to the ducks, and it is from here that Mr. and Mrs. Marat take off.

In front of the Boston ducks, even Captain America has to give way.

The bronze duck occupies the middle of the museum's gate, and parents and children passing by either step over or spare, and Captain America is the gatekeeper of the Doctor's Museum.

The first floor is a display point of rocks, ores, animal and plant specimens, Anna turned around, did not find interest, like a dinosaur or something, if it is alive, Anna may take a few looks, fossils and can't get hairy things, the big python at the door is alive, but it is not a rare species, it is not as good as a panda rolling will sell cute.

Anne Weaver walked around with Anna and found that she was not interested in anything on the first floor, so she suggested going up to the second floor.

On the corner from the first floor to the second floor, there is a huge photo of Howard Stark, this guy has almost all the major scientific inventions since 1940, presided over the research of the atomic bomb, built a large particle collider, participated in the Apollo moon landing program, if Captain America next to the duck is a symbol of the American spirit, then Howard Stark is the spokesman of the American scientific community.

As for the ornaments on the second floor, there are five or six related to Howard.

Apollo lunar module, Martian debris, artificial intelligence machines, etc., Anna has been wandering for a long time, like a rocket satellite model, she can calculate the geosynchronous orbit altitude, so just take a cursory look, and then go inside, it is medical electricity and other disciplines of equipment.

Not many adults came, but they were interested in children, a group of children gathered in front of the glow ball to touch and play, and then there was a weightlessness simulation, a wind tunnel with it, the most lively is the Apollo 11 lunar module, many children reached out to touch.

Anna was generally interested, and all she saw in her eyes now was a stone—uranium ore, standing on tiptoe, and her cheeks pressed against the glass for a while, looking like a greenstone, fluorite structure.

The madman teacher felt that Anna was out of place and reminded, "Anna, don't you go to the wind tunnel with your classmates?" ”

"Wind Tunnel?!" Anna shook her head, she saw that the nose and eyebrows of her classmates in the wind tunnel were blown together, it felt like an alien ET, it was so disgusting, it was hard for Anna to imagine what the flesh on her own face would be like when it gathered together.

"Anna is such a good boy, think about manual work." The madman teacher had been watching Anna look at the stone for a while, but she didn't understand what a stone was so beautiful, so she thought it was smart: "Uranium ore, it's very expensive, you can refine uranium metal." ”

Anna scoffed, the most worthless cubic uranium ore belonged to the things that no one picked up when it fell to the ground, and as for the yellow cake flour used to make the reactor fuel pellets, uranium octaoxide was not seen.

On the contrary, it is a test tube of heavy water placed on the glass display cabinet on the side, which looks no different from ordinary water, but in fact the price is tens of thousands of times more than ordinary light water.

Anna paid special attention to the small size of the nuclear reactor she was making, and the neutron moderator could only be used with light water.

"In the past, there were bituminous uranium mines and powdered uranium octachlor, but the museum eventually removed the samples because of the radiation from the parents." The tour guide explained.

The madman teacher agreed: "It's a responsible idea, and the child's health is the most important." ”

", nothing has radiation, even the turkey eaten on Thanksgiving has radiation, doesn't every family eat turkey. If others are worried, can't the museum hang a Geiger counter on the glass case, funny? ”

"Anna!" The madman teacher thinks Anna is rude and mocks the tour guide.

The tour guide made a "don't ask me, I'm just a tour guide" expression.

Anna didn't say anything more, and explained to stupid people that stupid questions are the most stupid behaviors, and parents reacted with radiation, not because radiation really hurt the child, but because they felt that it would hurt the child, and that feeling replaced objective judgment.

99.284% of natural uranium is uranium-238, and a small amount of other small amounts are the radioactive isotope uranium-235.

At that time, Marie Curie did not bring protective equipment, and directly stirred and stirred with a stirring stick in a large vat, and the radium chloride made from 8 tons of asphalt uranium ore did not live to be nearly 70 years old.
