Chapter 412 [Just the problem of funding is not a big problem]
Chapter 412 [It’s just a matter of funding, not a big problem]
The "Mirror of the Sky" proposed by Yu Qiu shocked Li Kang and Ning Xingqing, but the harsh demands she made afterwards made everyone present unable to sit still.
It is now almost the end of 2010, and it is required to be completed and operational by the beginning of 2015. There is only a little more than four years. This is not an ordinary demanding task, it is almost an impossible task.
At this moment, everyone at Xincheng University looked embarrassed and hesitated to speak. What they were most worried about now was that if they couldn't give Yu Qiu the answer he wanted, he might turn around and leave.
It is very likely that Xincheng University will miss out on this scientific research cake. Wouldn’t it be like a cooked duck watching it fly away?
Li Kang and others really couldn't figure out why the people from the Natural Science Foundation gave such a short deadline.
The people at Xinda didn't know it was because they had historical limitations, but Fang Hong, who had been reborn through time travel, knew that the LIGO experimental team in the United States next door would detect gravitational waves in 2015.
LIGO had built the device as early as 1999. Since then, it has been trying to detect gravitational waves, but it has never been detected. During this period, it has been upgraded many times. Until this year, when the LIGO device was completed, it still has not detected gravitational waves.
However, as the head of LIGO has applied for another US$400 million in funding from the American Science Foundation, and after further upgrades to LIGO, gravitational waves will be successfully detected in 2015.
There are not many substantive achievements in basic scientific research. Fang Hong spent so much money to get this achievement and cannot let LIGO take it away.
To say that the first detection of gravitational waves will bring any substantial benefits, in fact, it is not a benefit. It is more of a scientific honor and proves Einstein’s prediction a hundred years ago. However, if you really think so, it must be too late.
Its narrow vision.
Principal Li Kang who was present at the meeting asked: "What three factors?"
Time is too precious. Not only to deal with the solutions provided by the Natural Science Foundation, Ning Xingqing himself and Metro University also hope that the "Mirror of the Sky" project can be successfully completed.
Ning Xingqing continued: "The basic principle of space gravitational wave detection is to use the spacing of freely suspended test masses in space as a sensor to convert the gravitational wave signal into a signal of changes in the spacing of the test masses. To achieve the sensitivity required by a gravitational wave detector,
Depends on three main factors.”
Li Kang and others personally sent Yu Qiu and Fang Hong away from Xincheng University in a daze. Until the Maybach left the school, they were still in a daze. Especially Ning Xingqing, who had been engaged in research for most of his life and never dreamed of welcoming the new city.
Such a life opportunity.
Li Kang, Ning Xingqing and other people from Xincheng University were all dumbfounded, and their expressions read: I can't understand, but I am shocked!
As long as the chairman is satisfied and the chairman is satisfied, the rest of the chairman can be taken care of.
Speak concisely and clearly.
Therefore, fixing the chairman is the basis for fixing everything, and there is nothing wrong with it.
President Li Kang, who was the first to come to his senses, suppressed his excitement and immediately held a seminar with Ning Xingqing and others on this matter. This matter has undoubtedly become the most important top priority of Xincheng University.
In the following days, Ning Xingqing from Xincheng University led a team with more than a dozen other Xincheng University scientists to demonstrate the scientific and technological requirements of the "Sky Mirror". President Li Kang was also present at the meeting.
After saying that, she slowly left the living room and headed towards the bedroom. Her bedroom was on the first floor.
With this honor, it first shows that investing so much money is not in vain. Later, it can attract more talents to join, promote the progress of basic scientific research, further promote breakthroughs in applied research, and ultimately transform technological achievements that can be commercialized.
.
But these all mean a huge surge in the scale of project investment. To put it bluntly, it is too wasteful to rush for time. If a comprehensive evaluation is to find the most reasonable arrangement based on the actual situation, such a plan is generally completed in a 15 to 20-year cycle.
reasonable.
Good guy...
…
…
At this moment, Yu Qiu's smiling expression seemed to mean "Come on, praise me". Fang Hong glanced at her and said with a satisfied smile: "Well, you performed well, so you should be rewarded with one shot."
There is no breakthrough in the bottom layer, and it is impossible for the upper layer applications to produce any new results.
At this time, Yu Qiu glanced back at Fang Hong and gave him a look. Fang Hong understood what he meant. Well, what the chairman meant was that he needed to quench his thirst and quench his greed. Fang Hong calmly smiled and stepped forward.
go.
On the other side, the Maybach drove into Huayang Villa, and the two entered the Jingxinju Villa. After returning, Yu Qiu's temperament suddenly changed. She looked at Fang Hong and said with a smile: "How is it? I am a good chairman.
OK?"
The top priority now is to demonstrate the feasibility of the "Sky Mirror" plan.
At this time, Yu Qiu said calmly and confidently: "As long as it can be done technically, it's just a matter of funding. It's not a big problem. If the budget of 5 billion is not enough, we can add more."
It’s still a matter of funding, we need to add more money!
If there are sufficient funds, it will be different. The team size will be expanded several times and the division of labor will be more refined to improve efficiency. At the same time, you must be prepared for possible failures. For example, if there is a failure during the launch, then you must have a backup satellite, right?
The top priority is to demonstrate whether the "Sky Mirror" project can be realized by 2015. The Natural Science Foundation has given a one-month deadline, and the time is still very tight.
But at this moment, after Li Kang and Ning Xingqing whispered for a while, Principal Li turned to Yu Qiu and said cautiously: "Ms. Yu, if we want to meet your requirements and achieve operation in 2015, objectively speaking,
It is not impossible in theory or technology, but the required investment is probably far from enough even with a budget of 5 billion yuan."
Yu Qiu and Fang Hong looked at each other and said without concealment: "You want to send someone away with one shot? You have a good idea, at least three shots!"
All in all, Metro University must not miss the opportunity to lead the cooperation in the "Sky Mirror" project.
There is nothing that cannot be solved with one shot. If there is anything, then try another shot.
Before everyone could recover, Yu Qiu had already stood up. She looked at everyone and cast her eyes on Ning Xingqing and said: "Professor Ning, we hope that you will serve as the chief scientist of this project. Within a month, you will
Come up with an executable theoretical plan, and if the plan is approved, the Natural Science Foundation can allocate funds to launch the 'Sky Mirror' project."
"...The technical requirements are formulated based on the average gravitational wave detection sensitivity of observed celestial events. The ratio of the gravitational wave detection sensitivity h to the relevant interferometer arm length is [h=2δL/L]." at the seminar.
, Ning Xingqing listed a formula, and then said: "In this formula, L is the arm length of the interferometer, and δL is the arm length change, which is -1/2 power of mHz. But it should be noted that technology
The requirements are given by measuring the density of linear spectral lines in terms of gravity..."
Ning Xingqing answered: “The first is the arm length of the interferometer; the second is the ability to accurately measure the change in the distance between the two test masses; the third is the ability to measure and suppress other non-conservative forces except gravitational waves to ensure laser interference ranging.
The system effectively detects gravitational wave signals."
Everyone couldn't help but nodded, and Ning Xingqing continued: "The second issue is the measurement principle and payload. In order to realize a space-based interferometer, two sets of laser interference systems are designed on the mother spacecraft, one of which is used to detect the received signals.
Phase-locked amplification of weak light.”
"In order to better respond to the polarization characteristics of gravitational waves, a formation array of three satellites at the top of an equilateral triangle is used. Each satellite should be equipped with two test masses, which serve as the end points of the three interferometers to form two sets of inter-satellite
Laser interferometer. Space gravitational wave detection uses a freely suspended test mass as a sensor to convert the gravitational wave signal into a signal of changes in the distance between the test masses, which is the change in the arm length of the interferometer."
