Something about the echidna

The echidna is an animal known for its solitary behavior and unusual characteristics. It feeds on ants and termites, which it captures with a long, sticky tongue, similar to that of anteaters. It is covered in spines like hedgehogs and porcupines, lays eggs like reptiles, has a beak similar to birds, and a pouch like kangaroos. Additionally, it has a four-headed penis but lacks both nipples and teeth.

Despite the absence of sweat glands, it can withstand the extreme heat of its habitat, which includes Australia, Tasmania, and New Guinea. To cool down, it has developed a unique system: it releases mucus bubbles from its nose, which burst and moisten it, helping to keep it cool. These adaptations allow the echidna to survive and thrive even in climatic conditions that would seem lethal.

Along with the platypus, the echidna belongs to the oldest family of mammals still in existence.

💥 Your HPLC Columns Might Be the Real Drama Queens in the Lab

You’ve optimized your gradient. Your mobile phase is on point. Your sample is filtered to perfection. But your peaks still look like they’re having a meltdown?

👉 It’s probably your HPLC column acting up. And no one talks about it enough.

🧪 What Are HPLC Columns Actually Doing?

Behind that shiny steel exterior, HPLC columns are where the magic (or the chaos) happens. They’re packed with tiny particles that separate your sample based on interactions with the mobile phase — and every compound takes a different path out.

Basically, your HPLC column is running a tiny molecular obstacle course. And how well it works depends on the chemistry happening inside.

📊 Quick Guide to HPLC Columns (aka Choose Your Fighter)

Column TypeBest ForWhy You’ll Love ItC18 ColumnNon-polar compoundsThe classic reversed-phase beastC8 ColumnQuicker separationsLess retention, faster run timesPhenyl ColumnAromatic compoundsπ-π interactions for better selectivityAmino ColumnSugars & polar analytesWorks in both normal & reversed-phasePFP ColumnHalogenated & polar compoundsUnique selectivity, method-saver

💡 Pro tip: Choosing the right HPLC column can fix peak shape, improve resolution, and save you HOURS of troubleshooting.

🧼 How to Keep Your HPLC Columns Happy

HPLC columns aren’t indestructible. They’re sensitive, high-performance tools — and they demand respect.

✅ Always filter your samples & solvents ✅ Use a guard column (seriously, just do it) ✅ Avoid wild pH and pressure swings ✅ Don’t store them dry – use the right solvent ✅ Follow manufacturer guidelines like gospel

🚨 If Your HPLC Method Is Struggling…

Before you rewrite your whole method or blame the mobile phase, consider this: the issue might be with your HPLC column. A worn-out or poorly chosen column can wreck even the best method.

salad anon again with more kevward stuff (I am going crazy)

Kevin is president of student council, book club, chess club, and 2nd best cross-country (basically a school thing where you run a lot) player.

Edward is apart of the robotics club and doesn’t do much else.

but sometimes they have sleepovers and Kevin reads while Edward plays video games in comfortable silence before Kevin starts yapping about the contents of the book and Edward finishes/pauses his game to listen

Kevward… Sciencenerds (yes, that’s the dumbass ship name I came up with them)… I love them very much.

Scientific Method (Hypothesis)

An hypothesis is an unverified scientific explanation of relationships between facts based upon assumptions which may or may not be recognized by the scientists generating the hypothesis.

Quantum Speed: The Unimaginably Slow World of Relativistic Speed Duality

In this video, we discuss the concept of quantum speed, where a particle can move so slowly that continental drift appears fast in comparison. We explore the mind-bending idea of an accelerator that would be 5 trillion times more powerful than the Large Hadron Collider, and how a virtual light-speed particle would still take 179,000 years to complete the LHC's 17-mile track due to time dilation. We also discuss the double length contraction of the observer and the object, leading to a gamma value of over 63 quadrillion, resulting in quantum crawling at the quantum speed, where fast is slow.

Hi, science nerds; it's Drake, about to blow your mind with quantum speed. Imagine a particle moving so slowly that continental drift looks like the X15. We're talking about one billion years to move just 1.17 nanometers, one over c cubed. We'd need an accelerator to achieve this snail's pace; you heard that right, an atom smasher, but only one 5 trillion times more powerful than the Large Hadron Collider, whose speed duality is c minus the quantum speed. However, the virtual light-speed particle would take 179,000 years to round LHC's 17-mile track due to time dilation. However, due to the double length contraction of the observer and the object and a gamma value of over 63 quadrillion, it's still quantum crawling at the quantum speed, where fast is slow. Is your mind melted?
