first plastics made from synthetic components‚ Bakelite was used for its electrical non-conductivity and heat-resistant properties in electrical insulators‚ radio and telephone casings‚ and such diverse products as kitchenware‚ jewelry‚ pipe stems‚ and children’s toys. HISTORY: HOW IT CAME INTO BEING. Dr. Baekeland had originally set out to find a replacement for shellac‚ made from the excretion of lac bugs. Chemists had begun to recognize that many natural resins and fibres were polymers‚ and Baekeland

In establishing the presence of synthetic a-priori‚ Kant unleashed a new area of transcendental philosophy. The way in which Kant did this‚ however‚ assumes that judgements cannot be analytic a-posteriori. According to Kant‚ the limits of experience are transcendental; in this manner he believes himself to have to obey unknowable laws of thought. On the other hand‚ Hume did not believe in these limits. Synthetic a-priori knowledge is the pre-supposition which allows the transcendental philosopher

about what really makes us happy and what synthetic happiness is. According to Gilbert natural happiness is when we get something we want or we get exactly what we were trying to achieve for. For example getting an “A” on a paper you worked really hard on. Also another example would be getting the promotion you wanted at work. Gilbert also describes natural happiness as stumbling upon what you were exactly aiming for. In this video Dan Gilbert describes synthetic happiness as making the best out of a
