The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11Newtons (m2/kg2). Gravity and Everyday Objects ...

Evolving on a planet has warped our sense of physics.在一个星球上进化已经扭曲了我们对物理的感官。If I throw an object away from me, it comes back.如果我把一个物体扔出去，它会回来。That's bizarre! It should just keep going, moving away from me at a constant speed.这非常诡异的好吗！它...
traced back to the intersection between the science team’s and volunteers’ work: (1) science team–volunteer engagement; (2) mismatching temporal rhythms and divided priorities across the science team and volunteers; (3) retraining of ML models, and (4) the constant evolution of the GW ...
“Linear Motion”, presents a step-by-step technique to solve all linear motion problems when the acceleration is constant. This class is not essential for this course, yet the resolution technique presented is an extra “weapon” for students in feeling confident when facing a physics problem ...
High Energy Physics - TheoryA quantum theory of gravity is described in the case of a positive cosmological constant in 3+1 dimensions. Both old and new results are described, which support the case that loop quantum gravity provides a satisfactory quantum theory of gravity. These include the ...
casings. It's alien engineering but engineering that is not too distant from our own - and the basics of it are certainly understandable in our realms of physics. 这些飞行器的大部分结构由铝或铝合金制成,有时与其他材料层压以帮助其导电或储存电荷,有时还采用蜂窝结构,以增强强度和重量。同样在...
where c0 is a constant. To understand the physical behavior of the wave function, we plot its square in Fig. 1. This plot shows that the wave function has a large peak near some nonzero values of u and v, and smaller peaks after that. As the value of u increases, the smaller peaks...
Recently, a novel Einstein–Gauss–Bonnet gravity in four dimension has been proposed [1]. The theory is based on the action S=∫dDx−g(R−2Λ+α^D−4LGB), (1.1) where R is the D-dimensional Ricci scalar, and Λ is the cosmological constant. The Gauss–Bonnet term is given ...
