Regarded as a crackpot by his contemporaries and a genius by modern scientists, Charles Babbage (1792-1871) was the true discoverer of the principles on which all modern computing machines are based. His achievements have been virtually forgotten, but this compilation of his writings, in addition to those of several of his contemporaries, illuminates his pioneering work.Part I consists of selections from Babbage's long-out-of-print autobiography, Passages from the Life of a Philosopher, in which he recounts the pursuit of his dreams and remarks on noteworthy acquaintances, including Laplace, Biot, Humboldt, and Sir Humphry Davy. Additional features include articles, sketches, and letters by Babbage himself along with notes by his contemporaries that explain the principles and operation of the inventor's brilliant -- but never completed -- calculating machines. An informative Introduction places these writings in their historical context.

Baby loved them!
Flavor Name: Bone Broth Variety Pack, Size: 3.5 Ounce (Pack of 6)
Baby loved all the flavors! Perfect way to expose baby to diverse tastes and flavors. Tried some myself and they all tasted fairly good for being baby food.

Caused pooping spree
Flavor Name: Bone Broth Variety Pack, Size: 3.5 Ounce (Pack of 6)
Serenity Kids food pouches have caused my baby to have multiple pooping sprees. I bought the products due to the rave reviews and organic ingredients. But there are way too many ingredients in one pouch for a baby, and while everything looks clean, not everything is good for an immature digestive system. For example, apple cider vinegar might have been the trigger of one pooping spree. But there are so many ingredients in these pouches, making it hard to narrow it down. What has happened is that these and other Serenity Kids pouches have caused my baby to poop 4-5 times a day, at times 2 days in a row. It's awful to see the little one with a screaming red bottom and to hear her cry at the top of her lungs on the diaper changing station. Serenity Kids should be ashamed. For a company marketing itself as offering healthy foods to babies, it has failed spectacularly.

Funny
Flavor Name: Bone Broth Variety Pack, Size: 3.5 Ounce (Pack of 6)
Disclaimer: my review is nothing against the brand, I love Serenity Kids! I have been using the main starter pack with my (now 9MO) since he was 6MO. He has loved them all from the organic roots to the bison but dang, this "upgraded" pack threw him for a loop. Gagged at the beef pot roast. Probably won't be purchasing this variety pack again LOL
