Fingers Crossed for 2021 ...

2020 was the worst! COVID kept the museum closed for much of the year and a mains water pipe bursting causing a flood kept us closed for the rest.
We're hoping to re-open in the next few months ... fingers crossed! Read More >>>

No visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Or come and get involved on our social media channels ...

Thank you.

The hand-held pocket calculator was invented at Texas Instruments in 1966

The hand-held pocket calculator was invented at Texas Instruments, Incorporated (TI) in 1966 by a development team which included Jerry D. Merryman, James H. Van Tassel and Jack St. Clair Kilby. In 1974 a basic patent for miniature electronic calculators has been issued to Texas Instruments Incorporated. The patent is for personal-sized, battery-operated calculators which have their main electronic circuitry in a single integrated semiconductor circuit array, such as the popular "one-chip" calculators.
