Destroying the universe: How hard can it be?

In quantum field theory, the vacuum state refers to the lowest energy state in a system. Particles are excitations above this state and carry energy, hence the term "vacuum" to refer to the state with no particles. Nothing requires this state to be unique. There may be many different field configurations that are local energy minima, and hence stable against small perturbations. A local minimum that does not globally minimize energy is called a false vacuum. While locally it looks like a stable vacuum, it is unstable and will decay to the deeper, true vacuum. If the energy barrier between the false and true vacuum is high, however, then the decay rate is exponentially suppressed and the false vacuum may be very long-lived. Analogous behavior is common in other physical systems. Open a carbonated drink and the CO₂, more stable as a gas once the pressure is released, comes out as bubbles. But the bubbles take a moment to appear, and they form on the sides of the bottle rather than throughout the liquid. A bubble has to pay an energy cost to create its surface—the boundary between gas and liquid—and small bubbles have a larger surface-to-volume ratio. The energy gained by moving CO₂ into the gas grows with the bubble's volume, while the cost of its surface grows only with its area; so below a critical radius the cost wins and the bubble redissolves, and above it the gain wins and the bubble grows. Reaching that critical size takes a large enough chance fluctuation, which is why…

Gap Statistic Versus Total Sum of Squares For Cluster Centres (r language)

Hi I had a quick question about what to do when you encounter a situation where the optimal cluster center is different when you graph out the gap statistic and the total sum of squares. As I understand, you were supposed to take cluster center with the highest gap statistic and the center that is at the elbow of the total some of squares graph. Should I take both numbers suggested for the cluster centers for kmeans or am I'm doing something wrong? fviz_nbclust(iris_data, kmeans, method = "wss") # Le graph suggests that the optimal amount of cluster should be 4 where the elbow is iris_gap=clusGap(iris_data, FUN = kmeans, nstart = 25,K.max = 10, B = 50) fviz_gap_stat(iris_gap)

Because It Speaks In Words

There is a difference between knowing something, and truly understanding it. I think we've all had those moments, the ones where a truth you learned a long time ago really sits with you for the first time. It rests in your mind and stretches out, finally showing off the great expanse of nuance hidden deep within. Photo: mine. Most nights when you happen to spy the Moon, Jupiter, and Venus sitting in a line in the sky, you see them as the dots beside a crescent that they are. Yet sometimes, when framed amid the sunset sky above the wisps of silver cloud, you see them differently. You realize in that moment that you, your great-grandparents, Julius Caesar, and Aristotle all saw this same sky. It has always been for us. We know so much about Jupiter and Venus today, yet no human eye has ever seen more than you're seeing now. I think we are all, in this time, realizing the true power of words and what they mean, not to those who speak, but to those who listen. The Power of Stories It was Eugene Wigner who famously wrote about the unreasonable effectiveness of mathematics in the Natural Sciences, the empirical fact that advanced math is eerily accurate at predicting the behavior of nature, so much so that, for me, it can seem like mathematics is perhaps the true language that nature speaks. However, as children, we do not grow up with an innate understanding of complex mathematics, of this foundational language of nature. Instead we are all born with the innate desire to hear and…

Is AIC-based model reduction before adding latent class membership a defensible modelling strategy?

Is AIC-based model reduction before adding latent class membership a defensible modelling strategy?

I am an MSc Biostatistics student working on a study of willingness to quit smoking. I derived a 3-class latent variable using Latent Class Analysis (LCA) from FTND and two motivational indicators. Since these variables were used to construct the latent class, I excluded them from my logistic regression to avoid modelling both the component indicators and their derived latent construct simultaneously. I first fitted a full logistic regression using the remaining conventional predictors, performed AIC-based backward model selection to obtain a parsimonious model, and then added latent class membership to evaluate its incremental explanatory value using changes in AIC and BIC. Would you consider this a statistically sound and defensible modelling strategy? Are there any methodological references or alternative approaches that you would recommend?

Delhi EV policy to accelerate electric two wheeler adoption

The Delhi government on Monday approved a new Electric Vehicle (EV) Policy that is expected to accelerate electric two wheeler adoption through purchase incentives, mandatory EV only registrations from 2028 and a major expansion of charging infrastructure. The policy offers incentives of Rs 30,000 for electric two wheelers in the first year, Rs 20,000 in the second year and Rs 10,000 in the third year. From April 1, 2028, only electric two wheelers will be eligible for fresh registration in Delhi. Existing petrol and diesel vehicles can continue to be used as per the current rules. The move is expected to benefit electric two wheeler manufacturers such as Ather Energy, Ola Electric, TVS Motor Company, Bajaj Auto and Ultraviolette Automotive. Delhi is one of the country's largest two wheeler markets and the policy provides long term visibility for EV adoption. Reacting to the announcement, Tarun Mehta, cofounder and CEO of Ather Energy, said that Delhi has approved one of the most significant city level EV policies in India. "The combination of incentives, phased electrification mandates and charging infrastructure creates a very strong foundation. If Delhi can become a majority EV market, it has the opportunity to become a benchmark for the rest of the country," Mehta said in a post on X . He added that long term policies give the EV ecosystem the confidence to continue investments and product development. Narayan Subramaniam, CEO and Head of Design at Ultraviolette Automoti…

[Linkpost]Frame Error

Today I want to explain what I call “ frame errors ”: a third kind of mistake, distinct from logical fallacies and empirical errors. You can get every fact right and every inference valid, and still be wrong, because your framework for reasoning about the problem is structurally inadequate. In some sense, the idea is not new. Many other thinkers have pointed out specific instantiations of these mistakes before. However, I coin the “frame error” term to draw attention to the common category across these mistakes, provide tools and worked examples to help readers spot these errors when they occur, and offer advice to help readers understand and identify the meta-errors that might lead them or others to commit frame errors. This post will go through five common classes of frame errors, with worked examples. I will start with examples that you likely have heard of before, and then end with more novel examples where I was the first person to explicitly point out such errors. Along the way, I provide conceptual tools to model good thinking, so you can hopefully learn useful rationality and reasoning tips even if you do not buy the frame error construct.
