Living like a child, because world is my playground. Love to play game and watch e-sport. Interesting in data science, ML, Urban DBMS, GIS, Math and so on.

Another one of my small achievements to do in this game "Solo Sobek"
Fortitude role (Saki-Meryl-Lyra)

Greek letters pack precise meanings into single characters that scientists and engineers use to keep equations clear and concise.
They represent concepts like angular acceleration with alpha, beta radiation with beta, photons and the Lorentz factor with gamma, changes with delta, damping with zeta, efficiency with eta, angles with theta, conductivity with kappa, wavelength with lambda, friction with mu, random variables with xi, the circle ratio with pi, density with rho and stress with sigma.
These symbols come into play when teams calculate friction coefficients with mu during tire testing or assess material stress with sigma in aerospace component design.
It’s so lovely that I made this picture featuring all my favorite Final Fantasy characters in chibi selfie mode.

tensor algebra is not abstract math.
it is the grammar of modern intelligence.
a scalar is one number.
a vector is a line of numbers.
a matrix is a grid of numbers.
a tensor is the general form: numbers arranged across multiple dimensions.
images are tensors.
videos are tensors.
robot sensor streams are tensors.
neural network weights are tensors.
physics simulations are tensors.
deep learning is basically tensor algebra + optimization + compute.
once you understand tensors, AI stops looking like magic.
it becomes structure.
reality → numbers → geometry → transformations → intelligence.

If you’re still “prompting” Claude Code,
you’re missing the point.
Here are 26 Claude Code shortcuts that most users don't know exist:
SESSION CONTROL
/clear — wipes context and starts clean
/resume [session] — reopens a previous session by ID or name
/branch [name] — forks the conversation to explore a different path
/rewind — rolls back conversation and code to an earlier checkpoint
/rename [name] — renames the session. Leave it blank and one gets auto-generated
/export [filename] — saves the full conversation as plain text
MODEL & USAGE
/model [model] — switches to Sonnet, Opus, or Haiku mid-session
/cost — shows token usage for the current session
/usage — shows plan limits and rate-limit status
/extra-usage — unlocks extended usage when standard limits hit
PROJECT SETUP
/init — builds a CLAUDE.md project guide on first run
/memory — edits CLAUDE.md and controls what auto-memory saves
/add-dir <path> — adds a directory for file access during the session
/config — opens settings for model, output style, and preferences
CODE OPERATIONS
/diff — opens an interactive diff viewer for uncommitted changes
/security-review — scans pending changes for vulnerabilities
/plan [description] — enters plan mode before Claude touches anything
/permissions — sets allow, ask, and deny rules for every tool
AGENT LAYER
/agents — manages agent and sub-agent configurations
/skills — lists all available skills, built-in and custom
/plugin — manages Claude Code plugins
/reload-plugins — reloads active plugins without restarting
/mcp — manages MCP server connections and OAuth
/compact [instructions] — compresses conversation history, keep what matters
INTERFACE
/theme — switches between light, dark, and colorblind-accessible modes
/color [color] — sets prompt bar color for the current session
This is Claude Code, not https://t.co/EePliJpUip.
Different tool. Steeper learning curve. Higher ceiling.
⭐ Save this. Use it the next time you open Claude.
