Today is Ada Lovelace Day (ALD), an international celebration of the achievements of women in science, technology, engineering and math (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM.

Today is Loud Shirt Day, a day when we don our loudest shirts to raise awareness and money for kiwis who need to access sound with cochlear.
