I picked this one up from the Intute Science, Engineering and Technology New Resources feed. The Higher Education Academy Physical Sciences Centre have produced two data sheets for chemistry and physics students (the physics sheet might also be useful for 1st year engineering students).
Useful data for chemistry students
Published by the Higher Education Academy Physical Sciences Centre, this reference guide, in PDF format, includes: the periodic table, physical constants, units, algebra, trigonometry, weights, SI unit prefixes, logarithms, the Greek alphabet, indices, moles, gases, thermodynamics, mixtures, reactions, phases, kinetics, spectroscopy, electrochemistry, lattice energies, quantum theory, pH equations, and magnetic moments.
Useful data for physics students
Published by the Higher Education Academy Physical Sciences Centre, this reference guide, in PDF format, includes: work and energy, thermal properties of matter, motion in one direction, temperature and heat, waves, simple harmonic motion, momentum and impulse, rotational motion, quantum mechanics, torque, elasticity, electricity and magnetism, and gravitation.
