Pipeline: (1) DIMENSIONAL ANALYSIS forces the FORM from units 6// (the exponents), pruning everything impossible; (2) FIT the single dimensionless constant from data; (3) VERIFY exact 7// fit + GENERALIZE to held-out. Demo: rediscover kinetic energy KE = 1/2 * m * v^2 from raw (m,v,KE) observations + the 8// units of m, v, KE. The LLM is nowhere -- this is integer linear algebra (units) + least squares (constant). 9// T0 OBSERVATIONS: raw (m, v, KE) triples -- no law given. 10// T1 DIMENSIONAL FORM: units force m^1 * v^2 (the only dimensionally-valid product) -> KE proportional to m*v^2. 11// T2 FIT CONSTANT: least-squares c = sum(KE*f)/sum(f*f), f=m*v^2 -> c = 1/2 (the 500m). 12// T3 EXACT: residual 0 -- the discovered law fits every observation. 13// T4 GENERALIZES: held-out (m=5,v=2) -> 1/2*5*4 = 10, == true. 14// T5 = a multi-variable physics law DISCOVERED from data + units, fully mechanistic, NO LLM (Wigner-guided). 15// license_tier: ORIGINAL 16import "nx_f32_hw.nx" 17import "nx_syscalls.nx" 18 19func grow(name: *u8, ok: i64) -> i64 { if ok==1 { gw(" PASS " as *u8) } else { gw(" FAIL " as *u8) } gw(name); gw(" 20" as *u8); return ok } 21func gm(x: i64) -> i64 { return gn(f32_int(f32_mul(x, f32_of(1000)))) } 22func f32_abs(x: i64) -> i64 { return x & 0x7FFFFFFF } 23func f32_le(x: i64, y: i64) -> i64 { let d: i64=f32_sub(x,y) & 0xFFFFFFFF; if ((d>>31)&1)==1 { return 1 } if (d & 0x7FFFFFFF)==0 { return 1 } return 0 } 24// dimensional: a*units(in1)+b*units(in2) == units(out)?
