Weyl 's Predicative Classical Mathematics as a Logic - Enriched Type Theory . ( arXiv:0809.2061v1 [ cs . LO ] ) We construct a logic - enriched type theory LTTW that corresponds closely to the predicative system of foundations presented by Hermann Weyl in Das Kontinuum . We formalise many results from that book in LTTW , including Weyl 's definition of the cardinality of a set and several results from real analysis , using the proof assistant Plastic that implements the logical framework LF . This case study shows how type theory can be used to reprezsent a non - constructive foundation for mathematics .

A: What nay be the reason for the post ?

I took them by myself - this is the first time I have really gone anywhere with both of them by myself . It went okay , except that at the end of the appointment I forgot to wait for them to come in to do the vaccinations .

I ' ve been wanting to go camping all summer long but have been thwarted over and over again by forgetting tents , threatening rain and long work hours . The weather did n't look promising , but I was naive enough to believe the forecast of " 20 % chance " of rain . It started raining before we were even on our way .

A: Why does the narrator feel the trip was a dud ?

Her stilettos were off , and her hair had quickly been thrown up into a ponytail . Her eye makeup was smudged , and her lipgloss was a little smeared . The blouse she had worn to work was wrinkled , untucked and rolled up at the sleeves , and it looked like she had undone a few of the buttons around her neck .

Why is she hastily putting on clothing ?
