Leptopoecile sophiae

Is a tiny purplish-blue bird with a chestnut cap, a soft pink belly and a pale brow. They were first described by Nikolai Severtzov in 1873.

The species os resident in the Tian Shan and central China as well as in the Himalayas where it is mainly found in winter.

Family: Aegithalidae

Welcome to Iguanostalgia!

My name is Andrew Knight, a self-practiced artist from Vermont with a passion for all manner of extinct life. Here, on Iguanostalgia, I review the media that defined my dinosaur-crazed childhood.

Despite growing up in a region so devoid of dinosaur remains, my childhood was filled with all sorts of prehistoric imagery - be it Jurassic Park or Dinotopia, Disney’s Dinosaur or the Land Before Time - dinosaurs were everywhere if you knew where to look.

My upbringing took place in the early 2000s and there was mostly paleoart lingering from the “Dinosaur Renaissance”, which was a trend in science spanning from the 1970s to the 1990s. It was a time when the image of sluggish, swamp-dwelling behemoths were becoming replaced with new art of active, warm-blooded animals that were just as dynamic and fascinating as modern species.

On Iguanostalgia I revisit the books, films, exhibits, artwork and other dinosaur-related memorabilia that influenced most of my life.

Studying physics with no credentials and questionable intentions 😈

Hi there. I’m a hobbyist—no degrees, no credentials, just a deep love for physics, philosophy, and the architecture of ideas.

This blog is a space for speculative cosmology. I take existing frameworks from theoretical physics—like string theory, dimensional geometry, quantum mechanics, holography, etc—and explore them from alternative angles. I like to ask, what else could this mean? What might emerge if we loosen the constraints and follow intuition, logic, and pattern-recognition into uncharted territory?

Sometimes I braid different theories together. Sometimes I invent original perspectives that I haven’t seen others articulate yet, and everything I share is exploratory. I’m not claiming empirical truth—I’m offering frameworks and thought experiments. You’re welcome to take it with a grain of salt, and I hope you do 🖤

If you’re looking for mathematical proofs, this isn’t the place. I’m more of a logician than a physicist—I operate in the realm of conceptual structure, symbolic analogy, and recursive modeling. That said, I try to stay grounded in scientific ideas, even when I spiral into more abstract or intuitive territory.

You’ll probably notice contradictions show up from time to time; that’s because my ideas evolve! I’m always learning, so I might refine or abandon older concepts as I gain new information or unfold a deeper understanding. That’s part of the fun 😉

This blog is meant to be a playground, not a pulpit. This is a place to enjoy speculative thinking without needing to be right. If you’re skeptical of what I write—good! Skepticism is healthy. But please be kind. This space isn’t for arguing; it’s for exploring.

In my personal life, I’m also writing a sci-fi novel that explores many of these ideas through fiction. You can read the beta draft for free on AO3.

Thanks for being here. I hope you enjoy what blooms.

A research team from Northwestern University, alongside a team of professional underwater cave divers, just created the most complete map of the diverse microbial communities found in a lengthy submerged aquifer system in the Yucatán Peninsula.

Did you know that Black Hole would look a little bit blue to the side because of the Doppler effect? (Image is making process of Black Hole(Gargantua) in Interstellar)

What is Doppler effect?

Doppler effect is basically what makes the sound louder or more quite depending on how far it is from you. If it is closer to you it has higher pitch frequency, further from you - lower pitch frequency . The same with the light , for example we have a green light moving, if it gets closer to us , the frequency will be higher meaning the color we will see will be some kind of blue or purple. If it gets further away from us , the frequency will be lower meaning the color we will see will be red.

In case of Black Hole , some part of it will be closer to us , some further meaning some parts of it will be reddish some will be bluish

A Quick Guide to HPLC Columns and Their Role in Chromatography

HPLC columns are the heart of any High-Performance Liquid Chromatography system. Whether you're analyzing pharmaceuticals, environmental samples, or food contaminants, choosing the right column can drastically affect your separation efficiency, retention time, and resolution.

But what exactly are HPLC columns, and how do they work?

🔬 HPLC columns are packed with stationary phase materials like silica, C18, C8, PFP, phenyl, or amino groups. These materials interact with sample compounds differently, allowing each analyte to pass through at a distinct time — helping scientists identify and quantify each component with precision.

🧪 There are many types of HPLC columns, including:

C18 Column (Reversed-phase): Ideal for non-polar to moderately polar compounds

C8 Columns: Slightly less hydrophobic than C18, suitable for shorter retention

Amino and Silica Columns: Great for normal-phase chromatography

Phenyl and PFP Columns: Useful for aromatic or halogenated compounds

If you're involved in method development, QA/QC, or pharma R&D, understanding the right HPLC column selection is critical for success.

It covers column types, applications, and how to choose the best one based on your analytical needs.

Had a really interesting lecture about this and how obesity isn't really a choice given our current food landscape and how we are wired biologically, or at least not the type of choice people tend to imagine. It's way harder for some people to rid themselves of fat than others, even if it's at the level of it affecting their health and current quality of life. I've asked for a supervision with the lecturer to better understand this topic.

There's also different levels of fat that is able to be stored by every body, and once you reach that capacity that's when you start experiencing symptoms of metabolic syndrome. For example, lipodystrophy prevents people from storing and maintaining healthy subcutaneous fat (often only in certain areas) resulting in their stores being maximised and overloaded more quickly despite not necessarily having large amounts of fat on their bodies. This results in lipotoxicity (fats being stored in areas other than fat tissue, resulting in tissue damage ie fatty liver disease) and insulin insensitivity.

We also talk about metabolically healthy and unhealthy obesity, where the first is associated with hyperplasia of the fat tissue, and the second involves hypertrophy of fat cells and inflammation.

You know I wish fatphobia was less pervasive. Even among people who consider themself as progressive, it's rampant. So quick reminder. No it's actually not easy to stop being fat, and it sucks that we are treated differently for something we really can't control. Shaming a fat person for being fat, and shaming them for not having the "willpower" to become skinny- is bigotry. And if all you talk to fat people about is weight loss and dieting- congratulations! You're being a dick! Stop.
