    1. Running time is asymptotically tight bound. "Asymptotically" because it matters for only large values of nnn. "Tight bound" because we've nailed the running time to within a constant factor above and below.

    2. Running time has lower bound and upper bound once the number of computations get large enough.

    3. Computation takes time to run. The notation used for running time of computations is Big-Theta.

    1. What may not be expected in a country of eternal light? I may there discover the wondrous power which attracts the needle; and may regulate a thousand celestial observations, that require only this voyage to render their seeming eccentricities consistent for ever. I shall satiate my ardent curiosity with the sight of a part of the world never before visited, and may tread a land never before imprinted by the foot of man

      The "wondrous power" is, of course, the power of magnetism. Magnetism and electricity (not yet unified) are mysterious forces exciting scientists, adventurers, investigators, and the general public, all at that time. Physics, chemistry, and biology are all also jumbled somewhat together still.

      But the fact that these are fundamental forces of nature -- just like gravitation -- are clearly on display. As well, another theme and another question: "ardent curiosity." (Good thing or possibly bad?)

      Not many surprises here! Be careful what you wish for!

    1. 2020 has shown that Ioannidis’s claim does not apply to all areas of science. In amazing speed, bio-tech companies were able to make not just one but several successful vaccine’s with high effectiveness. Clearly some sciences are making real progress. On the other hand, other areas of science suggest that Ioannidis’s claims were accurate. For example, the whole literature on single-gene variations as predictors of human behavior has produced mostly false claims. Social psychology has a replication crisis where only 25% of published results could be replicated (OSC, 2015)

    1. Prof. Gavin Yamey MD MPH. (2021, April 20). I was very pleased to see Levitt resign yesterday from the science advisory board of the anti-vaxx group PANDA. Previously Sikora had resigned.

    1. There was no public forum for incremental advances.

      I've never thought of the academic paper as a format that enabled the documentation of incremental progress.

    1. Network science is now a mature research field, whose growth was catalysed by the introduction of the ‘small world’ network model in 1998. Networks give mathematical descriptions of systems containing containing many interacting components, including power grids, neuronal networks and ecosystems. This collection brings together selected research, comments and review articles on how networks are structured (Layers & structure); how networks can describe healthy and disordered systems (Brain & disorders); how dynamics unfold on networks (Dynamics & spread); and community structures and resilience in networks (Community & resilience).

      This is a great looking collection of articles on network science.

    1. Darren Dahly. (2021, February 24). @SciBeh One thought is that we generally don’t ‘press’ strangers or even colleagues in face to face conversations, and when we do, it’s usually perceived as pretty aggressive.

    1. In my dreams, I replayed the vivid experience of removing the brains from tiny skulls and slicing them up. Something about these nightmares was telling me not to continue down this road. Eventually, I mustered the courage to challenge my colleagues: what if the diseases we want to cure, and the answers we want, won’t be found in the mouse brain?

      Trustting our instinct on science brings fruits.

    1. Η δύναμη της επιστημονικής σκέψης δεν είναι οι απόλυτες βεβαιότητες και οι αλήθειες, αλλά η διαχείριση των λαθών και της εγγενούς αβεβαιότητας της ανθρώπινης σκέψης.

      Το έγραψε εξάλλου κι ο Αλ. Κροκίδας, 1 χρόνο πριν.

    2. όταν ακούμε τους πολιτικούς να λένε ότι για την αντιμετώπιση της επιδημίας «ακολουθούν πιστά τις οδηγίες της επιστήμης», δεν εννοούν παρά μόνο ότι «ακολουθούν τις οδηγίες κάποιων συγκεκριμένων ειδικών», οι οποίοι έχουν επιλεγεί να συμμετέχουν στις ειδικές κρατικές επιτροπές ειδικών όχι μόνο με επιστημονικά αλλά και με πολιτικά κριτήρια.

      Αυτές οι ρησεις των πολιτικων αρχηγών παιζονται στην λαϊκή αγνοια περί της επιστημης, των δυνατοτήτων (διαψευσιμότητα) και των αδυναμιών της (peer-review).

    3. Οι ανθρωπογενείς παρανοήσεις σχετικά με το «αλάνθαστο» και την «αυθεντία» του επιστημονικού λόγου, που εσφαλμένα συγχέονται με τη μεθοδολογική «αντικειμενικότητα» των επιμέρους επιστημών, ίσως αποδειχτούν τα πιο αποφασιστικά εμπόδια για την επαρκή και λιγότερο επώδυνη αντιμετώπιση της νέας επιδημίας.

      Scientists were not wong because they argued, - it was the people that thought so.

    4. Οταν δεν συμβαίνει αυτό, όταν δηλαδή οι επιστήμονες αθετούν ή, έστω, παραβλέπουν την αναγκαία μεθοδολογική και διαφωτιστική λειτουργία τους, τότε από ερευνητές της πραγματικότητας μετατρέπονται σε «ειδικούς», που αναλαμβάνουν τον ρόλο -αλλά όχι και την ευθύνη- της επίλυσης διάφορων προβλημάτων τα οποία, ενώ σχετίζονται με την επιστημονική τους αρμοδιότητα, ταυτόχρονα την υπερβαίνουν, λόγω των επιπτώσεων που θα έχουν στη ζωή των ανθρώπων οι «λύσεις» που εισηγούνται.

      "Ειδικοι" != Επιστημονες

    1. Programming is using a language that a machine can understand in order to get it to perform various tasks. Computer programming is how we communicate with machines in a way that makes them function how we need.
    2. Earning a computer programming degree can help you innovate and create solutions for a global society.

    1. ‘bold’ means to have many observational consequences

      As I said at the wiki I saw this link from, you don't test the hypothesis directly, you test the predictions, the "observational consequences", from the hypothesis.

    1. An allied science to lexicology is lexicography, which also studies words, but primarily in relation with dictionaries – it is concerned with the inclusion of words in dictionaries and from that perspective with the whole lexicon
