After adjusting the parameters in the middle of the night, the "Dragon Palace on the Sea" at this time can automatically adjust all the "wave petals" as sails according to the wind direction, wind speed and course, and Wang Guanshan has also completely taken over the driving work of the "Dragon Palace on the Sea".

Gu Xiaobai went back to sleep for a while, and when he got up the next morning, he heard that Pan Guoxiang had indeed started speaking.

"Ladies and gentlemen, this is the detailed content of Bernoulli's law just now, do you understand?"

The barrage flies wildly.

"Ako who seems to have understood......"

"Although I don't know much, as long as I see Mr. Pan's face, I feel that my knowledge is soaring. ”

"I understand the principle completely, although I still don't use it like this. ”

"I understand, Mr. Pan spoke so well, in simple terms, much better than our teacher!"

Pan Guoxiang glanced at the barrage, and felt that the number of people who understood it had accounted for about 20%, and he was not a professional, and there was no need to learn formulas and calculations, so he entered the next section.

Of course, the scope of application of Bernoulli's law is at low speeds, beyond Mach 0.3, it will deviate, because ultra-high speeds make the air compressed, and at this time a formula is needed to correct - the Carmen-Qian Xuesen formula. ”

Hearing this name, the barrage soared again: "Wow! Qian Xuesen!"

"Look at the name for a minute. ”

"Look!"

Looking at the netizens who typed the word "admiration" on the public screen, Pan Guoxiang felt a little emotional.

"Actually, physics is a lot like a relay game," he said. After clearing a stage, everything before you will have to adjust before moving on to the next stage. ”

On the public screen, there are fewer barrages.

"Everyone's energy is limited, but we have generations of physicists, constantly relaying, constantly approaching the limit, and then modifying the parameters, continuing to approach the limit, until finally reaching the limit of the era and themselves, passing the unknown puzzle to the next player. ”

Pan Guoxiang pointed out the window and said: "Everyone knows that normally, if it is downwind, the upper limit of the speed of the sailboat is the wind speed, and it is impossible to break through the wind speed limit, so for a long time, sailboats have been eliminated by modern power boats." ”

It wasn't until more than 200 years after Bernoulli's law was proposed that an American physicist named Bernard Smith proposed the concept of a modern high-speed sailing ship in his 1963 book "40 knots (74 km) Sailing". ”

But his theory was so far ahead of his time that it wasn't until 2007, 44 years after his theory, that a team broke through the 40 knots (74 km) speed, and when the team excitedly contacted Bernard to tell him that his idea had become a reality, Bernard was 97 years old. ”

On the barrage, everyone is also a little excited, and some are leisurely.

The scientific and technological progress of mankind is due to the efforts of countless pioneers.

"People are not satisfied with the speed of 40 knots, and with continuous efforts, the speed of the fastest modern sailing ship, "Sailing Rocket 2", has reached 119.95 kilometers!"

"Although this speed is far from the record set by those power boats that use rocket boosters to constantly challenge the extreme speed - 500 kilometers per hour, as a boat that does not need any additional energy, this speed can already be ridden on the highway!"

Pan Guoxiang's metaphor made everyone in a trance.

Many people have never been on a high-speed sailboat, but they have experienced the speed of a car on the highway.

"And just last night, Xiaobai led our team, for the first time to bring the design of rigid sails, hydrofoils, and keels to super-large ships, which may be another cross-era breakthrough, from today onwards, large ships are no longer just the patents of power ships, sailboats can also be at ultra-high speeds, across the ocean, sailboats can also carry heavy cargo, ride the wind and waves, sailboats back to the ranks of mainstream ships, maybe it's not far away......"

In a word, let alone the netizens who watched the live broadcast, even Gu Xiaobai was a little enthusiastic.

Gu Xiaobai turned his head, looked out the window, and then ...... The eyeballs almost bulged out.

Pan Guoxiang was still sighing, and he saw a group of people suddenly brushing up on the barrage.

"Teacher, teacher! out of the window!"

"I'll go, someone is dead outside the window!"

Pan Guoxiang turned his head to look over, and saw that not far from the window, there was a person dragging something like a parachute behind his back, hanging on the back and top of the Dragon Palace on the sea, like a kite off the line, rolling wildly in the air.

While rolling, he screamed.

"Help...... Ahh......hhh Help ......"

At this time, the place where Pan Guoxiang was located was the rear part of the "Dragon Palace on the Sea", the part of Area E.

This is the location of the generator, backup motor and other important mechanical equipment of the Dragon Palace on the sea, which belongs to the working area and is far away from the living and residential area.

In the rear, you can see the white waves dragged by the Dragon Palace on the sea.

Just now, Pan Guoxiang used this wave as the background to express his emotions.

In the barrage, someone has already said: "I just saw someone behind......"

"I saw it too, I thought it was the staff ......"

Pan Guoxiang was also stunned, he looked at the figure spinning wildly in the air: "This person, it seems to be the ...... of who"

Who's here?

Wait a minute...... It doesn't really matter who it is now...... The important thing is to save people quickly!

Time goes back a few minutes ago.

Wang Hongchun looked at Yan Xuexin with a confused expression.

"Really, are you really going to fly into the sky with this?"

This guy didn't sleep all night, and he tinkered with such a thing?

"That's right. Yan Xuexin looked like a matter of course.

"And, where did you get this parachute?"

"I picked up the scraps from ......the construction team to put it together," Yan Xuexin tugged at the rope, thought for a while, and said, "I may have borrowed a little material...... Oh, it's okay, I've already left a note, and I'll just lose the money to them when the time comes!

Can the business of a scholar be regarded as stealing?

Is that the case?

"But this thing...... Wouldn't it be dangerous?" Wang Hongchun was still puzzled.

"It's just a parachute at sea, this thing is probably the safest extreme sport......"

"No, what should I do if I am in danger......

"Don't worry, I've calculated everything, and the current speed is enough......" Yan Xuexin skillfully connected the sling on his body to a small crane in the rear, and then told Wang Hongchun: "You only need to help me do two things...... 1. Help me put the rope, 2. If something happens, help me shout for help!"

Then, Yan Xuexin checked himself.

"Life jacket, check, wind direction, check, wind speed, check, rope firmness, check!

Then a parachute flower bloomed, and Yan Xuexin flew into the sky.

Next Second......

"Ahh......h Help!"
