When you say topsoil, do you mean like gardening soil or something specific? The fertilizers and stuff seem like they would be bad for a snake…?
I mean straight-up dirt. For topsoil to use in snake enclosures, what you want to do is go to a gardening center and check the labels until you find yourself a nice bag of dirt. You want it free of additives and fertilizers and such; I always look for the organic stuff. Timberline and Kellogg are the brands I use.

Oh well huh, speaking of substrates and Egyptian etc.: here's a brand new article proposing a former Afrasian branch in the Balkans, substratal to Proto-Indo-European
and yes this does at least sound like it would work better than trying to make PIE and PSem neighbors, or projecting binary Semitic–IE comparanda into Nostratic. TBD if anything more comes of this idea later on…

What is the Difference Between SAW Grade Material and Optical Grade Material?
Optical grade materials are materials with low strain and no impurities, they are grown from the best raw materials at a relatively slow growth rate, and are often used in optical applications where the highest quality is required. Optical grade wafers are widely used in optical devices and require excellent optical performance.
SAW grade materials are primarily used in non-optical applications, and their growth raw materials rank second only to optical grade growth raw materials. The growth rate of this material is faster than that of optical grade material, which benefits mass production and cost-effectiveness.
In general, these grades of wafers vary in material quality and use. Optical grade wafers are considered to be of the highest quality, while SAW grade wafers are relatively lower in price. The selection of the appropriate wafer grade is crucial, depending on the specific application and material quality requirements.
FAQs of Wafers And Substrates
What is Epitaxy?
Epitaxial growth refers to the technique of growing crystalline layers with consistent crystal axes on a single crystal substrate, the epitaxial layer can be of the same material(Si/Si) or of different materials(SiGe/Si or SiC/Si).
What is the Pyroelectric Free Black LiNbO3/LiTaO3 Wafers?
We use a reduction technique to produce pyroelectric-free black LiNbO3/LiTaO3 wafers, which have a high ability to neutralize charges even if the electric potential occurs instantaneously. The pyroelectric effect of black LiNbO3/LiTaO3 wafers is almost eliminated and the transmittance is significantly reduced. The piezoelectric properties of black lithium niobate wafers are no different from those of standard wafers. Therefore, black-reduced lithium niobate wafers are widely used to produce higher-frequency surface acoustic wave devices.
What is the Difference Between Fused Silica and Quartz Single Crystal?
The key difference between fused silica and quartz single crystal is that fused silica contains non-crystalline silica glass whereas quartz contains crystalline silica. Fused silica is also known as fused quartz, it is a glass containing almost pure silica in an amorphous form. Quartz is a mineral compound containing silicon and oxygen atoms.
What is Single Crystal Substrate?
Single crystal substrate refers to the substrate materials used for epitaxial growth and the production of semiconductor devices.
What are Silicon Wafers Made?
Firstly, the silicon ore is purified to prepare polysilicon, and then the polysilicon is mixed with the dopant and melted for recrystallization to prepare a single crystal ingot. Finally, after ingot slicing, beveling, lapping, donor killing, polishing, cleaning, and other operations are performed to prepare silicon wafers with high flatness and surface cleanliness.
What is the Application of Silicon Wafer?
Silicon wafers are mainly used in various semiconductor chips, and then used in various electronic devices in daily life through various assembly, such as: TVs, computers, mobile phones, cars, etc.
What are the Advantages of Silicon as a Semiconductor Material?
1. The reserves of silicon on the earth reach 26.8%, second only to oxygen;
2. The energy gap of silicon is large (1.13V), which makes it have a higher operating temperature and lower leakage current;
3. The SiO2 layer on the surface of the silicon wafer can withstand high temperature and protect the silicon wafer.
What is the Relationship Between the Conductivity Type of the Silicon Wafer and the Dopant?
The dopants are mainly boron (B), phosphorus (P), arsenic (As), and antimony (Sb). Among them, the B-doped silicon wafer is P-type, which primarily conducts holes. The P-, As-, and Sb-doped silicon wafers are N-type and conduct electricity using electrons.

Can paper towel be an okay substrate for a snake long-term?
Paper towel is generally best as a short-term substrate, for when a snake is in quarantine or you need to keep a very close eye on their waste for whatever reason.
More natural substrates run circles around paper towel in almost every category, really. It's easier for snakes to perform natural behaviors, but you also have to swap out paper towel at least once a week, whereas if you're diligent about spot-cleaning, you can go months between deep cleans with natural substrates.
I only have a couple snakes that I keep on paper towel long-term for whatever reason, and it's just so inconvenient compared to other substrates. One snake I keep on paper towel (at least until he's at least two years old and has a stronger immune system) is my Mexican black kingsnake Ed, and I keep him on paper towel because he had a very persistent recurring tooth infection as a baby, so he needs to be eating in very sterile conditions and I need to know ASAP if there are any irregularities with his bowel movements. Even though it's necessary for him right now, I can't wait to change it because he's a very messy eater (in typical kingsnake fashion) and I feel like I have to change the towels at least a few times a week.
That's probably why it's so hard for me to get good pictures of him, now that I think about it - like every picture I get of Ed looks like this. Little black snake + paper towels that he likes to hide under = bad pictures.

Kammerzell 2005 had a theory that Old Ægyptian has many pairs of synonyms, where one is Afro-Asiatic, while the other is para-IE
which sounds like bullshit
Tumblr media
Oh fun, I think I've noticed one or two of these too; but yes a bunch of others immediately look like stretches, say, *ter- seems to mean primarily 'weak', only secondarily from there 'young creature', and specific 'child' only in a few still more derived reflexes like in Ossetic and Albanian.
I could imagine an IE loan stratum getting into Egyptian circa Sea Peoples; but also bare CC (or even single C!) root comparisons with PIE are a bit too easy to find, especially if we're apparently getting them from Pokorny instead of e.g. keeping any track of laryngeals.

First day of thesis work aaaa!
It actually wasn't that exciting in terms of the lab work I got to do, but it was exciting in terms of... everything else lol. I did the first synthesis and left the whole thing to crystallize (thesis supervisor said to forget about the solutions - apparently, they crystallize better when you aren't thinking about them ahaha). The entire day was a great challenge for my social anxiety and I'm very happy with how I handled things :) I'm exhausted though. I think I'll sleep supremely well tonight

Reminder to everyone that uses a sand/soil mix as substrate for their reptiles to very carefully check through as you’re mixing 😐
I don’t even know if this came from the soil or sand. I’m inclined to think soil, but I genuinely do not know.
