catalog.ngc.nvidia.com/orgs/nvidia/resources/resnet_50_v1_5_for_pytorch explains:
The difference between v1 and v1.5 is that, in the bottleneck blocks which requires downsampling, v1 has stride = 2 in the first 1x1 convolution, whereas v1.5 has stride = 2 in the 3x3 convolution.This difference makes ResNet50 v1.5 slightly more accurate (~0.5% top1) than v1, but comes with a small performance drawback (~5% imgs/sec).
Building blocks are a type of toy that typically consists of a variety of shapes and sizes of interlocking pieces, which can be assembled and stacked to create structures, figures, and scenes. They are often made from materials such as wood, plastic, foam, or other safe materials for children. ### Key Features: 1. **Variety of Shapes**: Building blocks come in various shapes, such as cubes, rectangles, triangles, and more, allowing for creative construction.
"Cleversticks" is a children's book written by David A. Adler and illustrated by Anna A. B. Hargreaves. The story typically revolves around themes of creativity, imagination, and self-expression, showcasing how children can engage with their environment in unique ways. The book encourages young readers to explore their own talents and interests.

Ciro Santilli 37 Updated 2025-07-14 +Created 1970-01-01Superconductivity is one of the key advances of 21st century technology:
- produce powerful magnetic fields with superconducting magnets
- the Josephson effect, applications listed at: Section "Applications of Josephson Junctions"
"Built to Rule" is a line of construction sets developed by Hasbro, often associated with their popular toy lines, particularly those related to the Transformers franchise. Launched in the early 2000s, the sets allow fans to build various vehicles and structures that are then used in conjunction with Transformers action figures. The sets typically feature a combination of building blocks and mechanical parts, allowing users to create custom designs while incorporating Transformers characters and themes.
Discrete quantum effect observed in superconductors with a small insulating layer, a device known as a Josephson junction.
To understand the behaviour effect, it is important to look at the Josephson equations consider the following Josephson effect regimes separately:

They used tin-oxide-lead tunnel at 1.5 K. TODO oxide of what? Why two different metals? They say that both films are 200 nm thick, so maybe it is:
-----+------+------+-----
... Sn | SnO2 | PbO2 | Pb ...
-----+------+------------
100nm 100nmA reconstruction of their circuit in Ciro's ASCII art circuit diagram notation TODO:
DC---R_10---X---GThere are not details of the physical construction of course. Reproducibility lol.
"Advanced Composite Materials" is a peer-reviewed scientific journal that focuses on the research and development of advanced composite materials. These materials typically consist of two or more constituent materials with significantly different physical or chemical properties that remain distinct at macroscopic scales. The combination often leads to enhanced properties such as increased strength, lower weight, improved durability, and better resistance to environmental factors.
Cobi is a brand known for producing building block toys, which are often similar in concept to LEGO bricks but with their own unique designs and themes. Cobi building blocks are compatible with LEGO bricks, allowing for creative construction using both brands. The Cobi product line includes a variety of themes, such as military vehicles, historical models, and architecture, often appealing to both children and adult hobbyists. Cobi blocks are typically made from high-quality plastic and feature a distinctive, brick-like design.
As of my last knowledge update in October 2023, "Conrad Models" could refer to various things depending on the context, as there are several companies and brands with "Conrad" in their name that focus on modeling, hobby kits, or simulation. One prominent example is Conrad Electronic, a company that offers a wide range of electronics components and model kits.
Construx typically refers to a brand of construction toys that allow users to build various structures and models using interlocking plastic pieces. These toys are designed to encourage creativity, engineering skills, and problem-solving abilities in children and even adults. Construx sets often include a variety of types of connectors and beams, enabling builders to create complex designs while helping to develop spatial awareness and fine motor skills. There are also many themed sets available that can be focused on architecture, vehicles, or other specific constructs.
EXÍN Castles refers to a series of strategic board games designed for two players. The game features a unique blend of strategy and tactical gameplay, where players use pieces representing castles to capture territory and outmaneuver their opponent. Each player aims to dominate the board by strategically placing and moving their castles while also taking advantage of various game elements. The game typically involves elements such as resource management, territory control, and tactical decision-making, making it appealing to fans of strategy games.
If you shine microwave radiation on a Josephson junction, it produces a fixed average voltage that depends only on the frequency of the microwave. TODO how is that done more precisely? How to you produce and inject microwaves into the thing?
The Wiki page gives the formula: en.wikipedia.org/wiki/Josephson_effect#The_inverse_AC_Josephson_effect You get several sinusoidal harmonics, so the output is not a perfect sine. But the infinite sum of the harmonics has a fixed average voltage value.
And en.wikipedia.org/wiki/Josephson_voltage_standard#Josephson_effect mentions that the effect is independent of the junction material, physical dimension or temperature.
All of the above, compounded with the fact that we are able to generate microwaves with extremely precise frequency with an atomic clock, makes this phenomenon perfect as a Volt standard, the Josephson voltage standard.
TODO understand how/why it works better.
Maximum current that can flow across a Josephson junction, as can be directly seen from the Josephson equations.
Is a fixed characteristic value of the physical construction of the junction.
The Ello Creation System is an interface and set of tools designed for creators using the Ello platform, which is a social network aimed primarily at artists, designers, and other creative individuals. Launched as an alternative to traditional social media platforms, Ello emphasizes artistic content and community engagement without the clutter of ads and algorithm-driven feeds. The Creation System typically includes features that allow users to showcase their work, collaborate with other creators, and participate in various artistic initiatives or challenges.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
