Talking about droplets and airborne. To him "airborne" meant long-range as in many kilometers. Droplet could be through the air more than 1 or 2 m. Plus, he said study it more! We have failed to do that.

Quick thread.

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

The Story of how Mary Slessor Stopped the killing of Twins but sadly died of Fever.

All you need to know

Retweet to educate someone

Killing new-born twins was common practice in the 19th century among the Ibibio people of Nigeria, but one Scotswoman went to great lengths to put an end to this.

Aberdeen-born Mary Slessor was one of the few missionaries in Africa who learnt the local language, adapted to the native customs and environment and gained the trust of the locals in order to make a truly positive impact.

Her father, a shoe-maker from Buchan, became incapacitated by alcoholism and Mary more or less became the breadwinner for the family.

Just that time he was very popular, he made a lot of decisions that laid the ground for his future dictatorship which he was cunningly planning for. Like civil servants’ union and university staff union were proscribed. This time, President's word was law and Moi took advantage

To compensate lack of charisma, Moi resorted to populist roadside decrees that would make people happy. In the process, he was making so many policy decisions at the spur of the moment. Some were so expensive to the country economically and politically
