Chapter 83: Igniting The Chinese Community
“After optimizing the trajectory prediction algorithm using the above method, its deviation distance can be reduced from the original 60,000 kilometers to around 6,000 kilometers.”
Lin Ran put down the chalk and said to the dense formulas on the blackboard.
The people in the audience first from the front row, then from front to back, burst into polite applause.
Lin Ran’s formula was very beautiful, making everyone marvel that it was indeed worthy of a mathematics master, with the calculus applied perfectly.
Although not all of the NASA high-level officials present were proficient in calculus, at least they were all senior talents who had received modern mathematics training, and they could tell if the model built by Lin Ran was good.
Combined with Lin Ran’s prediction for Freedom 7, compared to James Webber, everyone was at least convinced by Lin Ran.
After the applause stopped, Lin Ran continued: “Not enough yet.
This is still not enough.
We still need to do a second step of optimization on it.
The algorithm cannot achieve perfect prediction of the initial trajectory because the rocket’s flight trajectory will always encounter various accidents.
Whether it is the vibration of the rocket itself during launch or the uneven phenomena that may exist in the burning process of fossil fuel, these will all lead to the accumulation of errors.
At such times, we need to enhance the efficiency of ground calculations.
What we are using now is the IBM 704, which takes hours to do a single trajectory simulation.
We should pre-simulate combinations of different launch angles and speeds in multiple scenarios, make the calculation results into a trajectory lookup table, and reduce the process of real-time calculation.
Additionally, during input, adopt a method of one person inputting and one person verifying to reduce the error rate of punch cards.
I see that Los Alamos Laboratory has already achieved this, so go contact them and have them come teach the experience.
Finally, optimize the launch window, choosing the time when the moon is closest to perigee to further simplify the trajectory calculation.
With these three working together, the deviation of Pioneer 4 can be reduced to 0, allowing it to successfully land on the moon.”
At the end, Lin Ran drew two balls and one rocket on the remaining bit of blackboard, then used a dotted line to connect the rocket and the small ball together.
“President Kennedy will hold a hearing in Congress in August facing all senators and congressmen, which will relate to NASA’s full-year budget next year. We need to send Pioneer to the moon before that.
Tell the congressmen in Washington that NASA not only has precious experience, we also have successful experience.
There is no word ‘failure’ in my life. Webber Director and I came to NASA to bring you one success after another!”
James Webber in the audience stood up first to lead the applause, others successively stood up to applaud, and this time the applause carried some sincere meaning.
Because Lin Ran gave a complete solution for Pioneer moon landing around it, and from their perspective, this solution might not guarantee moon landing success, but at least it had a grasp of success.
Unlike before in NASA internal, where there wasn’t even a grasp of success, wanting to skip hard landing and directly develop soft landing.
Lin Ran’s speech was full of explosive points, whether it was saying all the NASA high-level officials present were trash, or that NASA would land on the moon in just two months, or Lin Ran saying he would bring NASA one success after another.
In short, any of these points could attract the public’s attention.
Among them, the New York Times front-page headline read as follows:
“Chinese descent mathematician points out NASA is all trash, yet receives full audience applause
White House Special Assistant for Aerospace Affairs Randolph Lin recently at NASA’s closed-door meeting directly pointed out that NASA only has so-called precious failure experience, and directly pointed at all the scientific researchers and engineers present as all trash, his original words being:
‘I’m not saying who, I’m saying all of you present are trash.’
After publicly mocking, Professor Lin demonstrated the orbit prediction model to NASA and proposed a three-fold optimization proposal for the moon mission.
Pioneer probe may become America’s first moon lander.
James Webber Director afterwards in an interview with a local Washington newspaper strongly supported: This is not a gamble, but precise mathematics.
‘This is equivalent to letting the rocket carry a map for all possible lost paths to fly to the moon.’ Jet Propulsion Laboratory Director William Pickering sighed afterwards.”
After this news was leaked to the media by NASA internal high-level officials, various newspapers rushed to report it, and after American media reported, it spread all over the world.
Especially in places with Chinese people, it caused a far beyond imagination intense reaction.
Section Chief Zhang at this time had already joined the joint venture company named Hong Kong Shipping established by Hong Kong Chinese shipowners together, as a new sailor of this company.
Because of his strong body, rigorous work attitude, and excellent learning ability, he quickly got the opportunity to go to sea.
However, he couldn’t participate in the most advanced brand new standardized shipping route, because that route required old-timers who had worked under Xu Aizhou or under Dong Haoyun for more than ten years.
Newcomers like Section Chief Zhang could not gain trust.
“A Yuan, I remember you can read, right? Come, come, this newspaper is so uplifting for us Chinese people!
Take a look.”
This day they were changing cargo at Yokohama Port, the first mate saw him blowing wind on the deck, specially walked to his side, and handed the newspaper to Section Chief Zhang who was using the alias Chen Zhiyuan.
To match Chen Jingrun’s identity, the identity arranged for Section Chief Zhang was that of a fallen landlord’s descendant.
Section Chief Zhang took the newspaper from the other’s hand, Overseas Chinese Daily, the front-page headline was someone familiar to him, and also the core reason he was in Yokohama instead of Yanjing:
Lin Ran
The Overseas Chinese Daily’s front-page headline praised Lin Ran as unparalleled in heaven and earth.
Saying that all NASA high-level officials combined were not as good as Lin Ran alone, that the moon landing NASA couldn’t complete in three years, Lin Ran could do in two months after coming.
Currently Lin Ran only said to land on the moon, but Overseas Chinese Daily already spoke as if it had already landed on the moon.
After Section Chief Zhang finished reading, he handed the newspaper back: “Too amazing, worthy of the light of the Chinese people.”
The first mate nodded: “All the whites sitting below were pointed at the nose by a Chinese person saying they were all trash, not only could they not refute, they had to applaud along.
Because Professor Lin is just stronger than them.
This scene, just thinking about it feels great.
Unfortunately, why were there no reporters taking photos on site, it would be good if there were photos.
Best if it’s a photo of Professor Lin pointing at their noses scolding.
No way, this is indeed too great, need to have a good drink.
Come on, go find an izakaya with me for a good drink, anyway the ship leaves tomorrow.”
Section Chief Zhang agreed while thinking, “Professor Lin is indeed Professor Lin, is there any way I can get the full text of his speech inside NASA?
The theory he proposed is so amazing, it must be very helpful to China as well.
After arriving in New York this time, I probably need to find an opportunity to contact my ‘good son’.”
