How does this batch differ from the physics/color batch?

That guide covered sphere surface area, Morse, Base58, and WCAG contrast. This set adds chemistry and thermodynamics, readability indices, SHAKE/CRC24, split Base64url encode/decode, and UK NHS number checks.

Are all 100 pages linked here?

No—each section points to representative tools. Browse Math, Writing, Security, Encoding, Protocol, Schedule, and Identity tabs for the full list.

Can agents prefill these tools?

Single text fields often accept q or qb. Multi-field physics, date, and header tools open without URL prefill.

Science, text, and header tools — what to open when

Another hundred tools landed across seven themes—physics and chemistry, text normalization and readability, extended hashes, encoding helpers, HTTP security headers, calendar math, and supply-chain identifiers. Start here when you know the job, not the route name.

The newest Toolcore batch adds another hundred browser-local pages in science and chemistry math, text readability and case utilities, extended digests, encoding helpers, HTTP security header parsers, calendar countdowns, and identifier format checks. Use this map when you already know the task—not when you want to scroll the full catalog.

Physics, chemistry, and thermodynamics

Hyperbolic sine, harmonic oscillator, and pendulum period — mechanics and oscillation homework.
Ideal gas law, Boyle's law, and Charles's law — gas-law drills and lab prep.
pH calculator, buffer pH, and half-life decay — chemistry and nuclear decay estimates.
Dew point, wet-bulb temperature, and relative humidity from dew point — weather and HVAC sanity checks.

Case, readability, and pasted text cleanup

Normalize prose before publishing or scoring readability—everything runs locally on pasted text.

Leetspeak encode, grapheme count, and UTF-16 length.
Flesch–Kincaid grade, SMOG index, and Coleman–Liau.
Sentence case, title case, strip markdown, and find URLs in text.

Extended hashes, HMAC, and strength scoring

SHAKE128, SHAKE256, Tiger128, and Whirlpool512.
HMAC-MD5, HMAC-SHA384, and CRC-24.
Passphrase strength, password strength score, and memory estimates for scrypt / Argon2.

Base32hex, Base64url, and escape helpers

Base32hex encode / decode — hex alphabet variant without padding confusion.
Split JWT-friendly pages: Base64url encode and decode (the combined tool remains at /tools/base64url).
ROT13 decode, ROT47 decode, and SQL string escape.

HTTP security and cache header parsers

Host, Origin, and Vary — split pasted header lines.
Strict-Transport-Security, Permissions-Policy parse, COOP, and COEP.
WWW-Authenticate and Proxy-Authenticate — challenge scheme breakdown.

Calendar countdowns and identifier formats

Days until date, weeks until, add days, and subtract days.
Supply-chain and public-sector IDs: NSN format, UIC, GLN, CAGE code, and NHS number check.
