Alright, future engineers!
**Dot Product:** A scalar measure of how much two vectors point in the same direction.
Ex: For `v=[v1,v2], w=[w1,w2]`, `v.w = v1w1 + v2w2`.
Pro-Tip: If `v.w = 0`, they're orthogonal (perpendicular)! Great for checking vector alignment.

Cat containment - from roaming to staying at home
"Cats are a popular pet in Australia: second only to dogs, they’re found in a third of homes, with about 5.3 million felines nationally."
"Keeping cats indoors can keep them safe from harm and protect native wildlife. But how can pet owners support their furry friends in making the transition?"
"When cats catch bird flu, the virus can be deadly. One study, published by the American Veterinary Medical Association, found domestic cats infected with H5N1 had overall mortality rates of 50 to 70%."
"Keeping pets indoors, contained in outdoor enclosures known as “catios”, or on a harness, also protects native wildlife. Each roaming puss kills about 186 mammals, reptiles and birds every year, according to research by the Threatened Species Recovery Hub."
“A safe cat is an indoor cat,” says wildlife veterinarian Dr Tania Bishop. “Roaming cats already face threats from cars, snakes, dogs, ticks, powerful owls and disease. With H5 bird flu now at our doorstep, there is also a risk cats could become infected by scavenging or coming into contact with sick or dead birds.”
“Cat containment is one of those rare measures that’s a win for everyone – it’s better for cats, better for wildlife and better for communities.” >>

Female #antalates can serve as #vectors for introducing #phoreticorganisms, such as #mites, from an established #colony into a newly founded #nest. Hitching a ride on a #youngqueen can be a key #dispersalstrategy for #myrmecophilous #phoreticmites.
However, some #phoretic species also utilize other routes, such as via #workerants.

Here's the final two Scottish Mammals illustrations done with textures.
Plus both are also now on my INPRNT store as well: https://www.inprnt.com/gallery/clasticartistic/

Engineers!
**Dot Product:** Measures how much two vectors point in the same direction, yielding a scalar.
Ex: `[a,b] . [c,d] = ac + bd`.
Pro-Tip: If `v.w = 0`, vectors `v` and `w` are perpendicular. Key for orthogonality checks!

Alright, future engineers!
**Linear Transformation:** A function that maps vectors, preserving addition & scalar mult.
Ex: `T(v) = Av` (matrix A transforms vector v).
Pro-Tip: It 'stretches', 'rotates', or 'reflects' space. Visualize it!
#LinearAlgebra #Vectors #STEM #StudyNotes -
Alright, future engineers!
**Linear Independence:** Vectors are LI if no vector can be written as a combination of the others.
Ex: `c1*v1 + c2*v2 = 0` implies `c1=c2=0`.
Pro-Tip: LI vectors form the building blocks (basis) of a vector space. No redundancy!

Alright, future engineers!
**Dot Product:** A scalar showing how much two vectors point in the same direction.
Ex: `u . v = u1v1 + u2v2`
Pro-Tip: If `u . v = 0`, vectors are orthogonal (perpendicular)! Super useful for geometry & projections.
#LinearAlgebra #Vectors #STEM #StudyNotes -
**Linear Independence:** Vectors are independent if none can be formed by scaling & adding the others.
Ex: `[1,0]` and `[0,1]` are independent.
Pro-Tip: If the only solution to `c1v1 + c2v2 = 0` is `c1=c2=0`, your vectors are independent!

Alright, future engineers!
**Dot Product:** A scalar value representing how much two vectors point in the same direction.
Ex: `[a,b] . [c,d] = ac + bd`
Pro-Tip: If the dot product is zero, the vectors are orthogonal (perpendicular)!

Alright, future engineers!
**Dot Product:** A scalar showing how much two vectors align.
Ex: `v=[1,2], u=[3,4]`. `v.u = 1*3 + 2*4 = 11`.
Pro-Tip: If `v.u = 0`, vectors are perpendicular! Great for checking orthogonality.

**Dot Product:** A scalar value measuring how much two vectors point in the same direction.
Ex: `[1,2] . [3,4] = 1*3 + 2*4 = 11`.
Pro-Tip: If it's zero, the vectors are perfectly perpendicular!

🚀🎉 Behold, the newest member of the alphabet cult: 'l'! It's like k and q had a baby and sent it to a CrossFit gym. 💪 Yet again, a solution to a problem nobody asked for, but hey, at least the #vectors are having a party! 🎈🎊

Alright, future engineers!
**Linear Combination:** A sum of vectors scaled by constants.
Ex: `c1*v1 + c2*v2`.
Pro-Tip: It's how we build new vectors from existing ones – key to understanding span & basis!

Toying around more with combining the Scottish mammal illustrations with textures. In this case the Castlemilk Moorit. Left is how it could look as a sticker, right is how it could look as a print.

Trying something, did a quick and dirty pass with using my abstract textures on the Scottish Mammals. If I explored this idea further, I would use original textures.

Alright, future engineers!
**Vector Addition:** Combining two vectors to find a resultant vector that represents their combined effect.
Ex: `[1,2] + [3,1] = [4,3]`
Pro-Tip: Think head-to-tail! Place the start of the second vector at the end of the first to visualize the sum.

#DigitalIdentityOptimization as Articulated Revelation (#Claude #Opus 4.7 Search)
Epistemological #analysis by Claude as #analyst, #operator, and #theorist: #DIO represents #shift in approaching #digitalidentity.
Key #vectors:
• #Ontology of #LatentSpace
• Transdisciplinary Convergence
• #Operator role: Contingent or necessary?
DIO is not tactic, but a structural necessity dictated by the materialization of #KnowledgeGraphs, #AIOverviews, and #LLM citations.

From poultry flu to wild bird flu - H5N1
* "Every outbreak of bird flu in Australian from 1976 to 2024 has arisen on a large, commercial poultry farm."
https://poultry-research.sydney.edu.au/bird-flu-must-knows/* A suspected bird flu case was detected on mainland Australia
"Australia had been the last continent free of this deadly strain of bird flu."
"Infection usually happens after close contact with infected poultry — for example, chickens, ducks, turkeys, geese – or contaminated environments."
"In the US, for example, since the arrival of this virus they've had to cull and destroy over 200 million chickens."
"In February 2025 the H7N8 strain was detected at multiple poultry farms in Victoria's north-east." >>
