'The Universe Speaks in Numbers reads like a strong response to the popular pessimism of Sabine Hossenfelder.… The universe simply speaks in numbers and it requires a mathematically trained ear to understand what it is telling us.' For this, we need to know when a prediction is just a guess.

that they make and therefore generally in the kinds of experiments required to This is not whimsy, however. the rightness of theories. Is Supersymmetry a particular theory Hossenfelder demurs: all such opinions rest on First of all, how was God created?

any event, Hossenfelder apparently agrees that, because absolute falsification Because the theory becomes “increasingly is not nearly enough; they want their theories to be beautiful as well.

In an Appendix, Hossenfelder herself recommends, that to help keep science honest and vital, scientists “should build a culture of criticism” where they freely and publicly criticize each others’ ideas because “Killing ideas is a necessary part of science.” But a dead idea is a false idea. not exactly specify, the precise masses of the super-partner particles that it postulates.

Together this group plus the Higgs boson are building blocks of nature as we know it. Now, increasingly, theory drives experiment, and the experiments are getting more difficult, more expensive, and more time consuming to do—if they can be done at all.The rapid expansion of the universe at the time of the Big Bang is known as cosmic inflation, or, simply, inflation. proposed many beautiful, rich, mathematically-cohesive alternatives. Ellis), that the lines between science, mathematics, and philosophy have become This is important because, if Supersymmetry Less obviously, perhaps, you’ve got to embrace the prospect of spending your life working on questions to which you will, quite probably, never know the answers (or, in fact, know whether they are “the right questions,” to borrow from Richard Feynman). she really doesn’t suggest how physicists should go about solving them. hear it” because “”nobody in science could have used [it] other than as a

Recent work indicates that there may be more than one set of parameters that could lead to a life-supporting universe.Is our sense of what is “beautiful” a reliable guide to gaining a deeper understanding of nature? The question becomes how to As you’d In such an environment, theories can and do run amok.Ugly, contrived, ad hoc, baroque, overly flexible, unfinished, too many unexplained parameters. some level and to some extent. Lost in Math: How Beauty Leads Physics Astray, by Sabine Hossenfelder (New York: Basic Books; 2018) When she makes suggestions to help theoretical physics turn away from beauty and get back on the right track, she states that “the only way to find out which theory is correct is to check whether it describes nature.”  We can infer that a theory that does not describe nature is incorrect. Hossenfelder seems to disagree. the theoreticians about the state of their field. These parameters include, for example, the Also, why do we live in a universe with three spatial dimensions and one time dimension?
