On the other hand, if we consider an infinitesimal rescaling \Omega = 1 + \omega \approx 1, we might write \begin{aligned} \delta _{\omega } \Gamma= & \int d^4 x \ \! \left[ \frac{\delta \Gamma }{ \delta h^{\mu \nu }} (-2\omega ) h^{\mu \nu } \ + \ \frac{...
Write an SQL query builder in 150 lines of Python! 20 minute read This is the fourth article in a series about writing my own SQL query builder. Today, we'll rewrite it from scratch, explore API design, learn when to be lazy, and look at worse and better ways of doing things –...
For the purpose of this work, we assume that the function f\left( R,{\mathcal {T}}\right) is separable and linear in both R and {\mathcal {T}}, i.e., we write \begin{aligned} f\left( R,{\mathcal {T}}\right) =R+\gamma {\mathcal {T}}, \end{aligned} (6) where ...

Why did I write this article? Most people don’t understand the difference between fundamental physics proving the “greenhouse” effect (AGW), and climate catastrophe. I didn’t say they don’t understand the difference between fundamental physics and a nuanced view ...
and rewrite the original 𝐤 integral of Equation (19) as the trivial identity ∫𝐤𝐼=∫𝐤𝐹+∫𝐤𝑁+∫𝐤𝜃(𝑘−𝑘¯)(𝐼−𝑁−𝐹)+∫𝐤𝜃(𝑘¯−𝑘)(𝐼−𝑁−𝐹), (24) with 𝑘¯ being a conveniently chosen wavenumber such that 𝜔<...
We have now all the ingredients to rewrite our actions for GR and TEGR in the vierbein formalism. To obtain the second order vierbein formulation of the Hilbert action, we would simply insert the definition of the metric gµν = ηabeaµebν into (8), and write R(@a) instead ...

(11)–(13), we can rewrite the temperature in terms of S and P as(23)T=14πS[1+8SP−πq2S+m2cc1Sπ+m2c2c2]. Considering the Eq. (23), one can write the pressure as a function of T and S in the following form(24)P=πT2S−m2c2c2+18S+πq28S2−m2cc18πS. On the...
